Technical matters

It has always been my intention to lay out some of the background of the server, how it came to be, why it is the way it is and why it isn't better but will be someday. Unfortunately, that's the sort of project that tends to get shunted aside as more pressing needs are dealt with. Rather than drop the idea altogether, I've decided to dump some rather ill-organized and incomplete chunks of text into this document in hope that (a) someone may find something of interest here and (b) maybe I'll slowly add to it until it starts to cohere into something worth reading. If not, all we've lost are a few moments and some mental confusion :-)

Anyone preparing pages for CoOL should read the guidelines for authors.

Summer 1987 Conservation DistList begins operation

A flier was posted on the (non-electronic) bulletin board at the 1987 AIC Annual Meeting, inviting people to participate in the nascent DistList [I am not certain about this, but I think it is accurate]. Over the summer a very few people responded and discussions began. The message traffic from the first few months was not saved. Originally the list ran on forsythe, a mainframe at Stanford (an IBM 3090 running MVS, for those who care). It started out as a manual-implementation-reflector. That is, people would send messages to me personally, and I'd send them out to a list (which was implemented as very crude macro-expansion). Sometime during the first year, the few dozen participants agreed that a digest would be preferable.

The first message in the DistList archives 28 Oct 87, from Robert Espinosa is not actually the first DistList message, simply the first one retained. The "instances" of the first year, as they appear in the archives, are reconstructions. That is, they do not reflect actual digests as they were mailed out, especially the first one (the later ones during that year may, in fact, be "real").

Since the first year, the DistList's "emission cycle" (ok, "volume year") has begun around the time of the AIC Annual Meeting.

At the time of its first messages, there were no museum- or archive-oriented lists on the Internet and there was only one library-oriented list, Notis-L, (a list devoted to Notis, an Integrated Library Package), hence my claim that the DistList was the first library, museum, and archive-oriented list on the Net. Very shortly later (within months) PACS-L appeared and very rapidly grew to be a major list with a huge subscribership).

Sep 1988 Cons FileList announced

The Cons FileList was a small-scale document distribution service. It was always a strictly manual operation; people would send me email requesting a document and I'd email it to them. My initial note about this could be considered the hint of the future development of Conservation OnLine:

I was just gearing up to writing a thing for the distlist suggesting that we make available to eachother textfiles that might be of general interest. we all spend a great deal of time writing things like specifications, evaluations of processes, course notes, and other documents that could be of some use outside our own institutions. If these things were prepared on a machine, it is no big deal to send them over the net. If people are interested, I would be glad to store such docs and handle requests for dissemination. Or we could simply announce availability via the distlist. If there were very enthusiastic interest in this, we could even set up a server (an account running a special program to handle file requests), but that's probably for the future...

Summer 1990 I mention to Eleanore Stewart that I hoped that the DistList participant list would grow to 100 people by the end of the yearly cycle (by June 1991)
May 1991 DistList participation list grows to 202 people.
May 1992 Ellen McCrady contributes "List of Permanent Papers, Standards Met, and Main Use" to the Cons FileList. I believe this is the first Abbey Publications presence in CoOL
Feb 1993 CoOL WAIS Servers publically announced.

The following databases were part of the initial roll-out. All were publically registered with the global WAIS Directory-of-Servers. For much of its history, CoOL's WAIS servers constituted 1-2% of the registered WAIS servers.

cool-directory-of-servers (top-level directory for Conservation OnLine (CoOL), basically used to determine which of the other databases to use
cool (Archives of the Conservation DistList)
cool-cfl (Text files formerly provided by the Conservation FileList)
cool-cdr (The ConsDir: Conservation Email Directory)
cool-net (General information on networking)
cool-lex (lexical and classification material)
cool-bib (Bibliographies)
cool-ref (Citations)
Feb 1993 Pat Battin gave permission for SUL to mount Commission on Preservation and Access documents.

Later that February we discovered that none of CPA's documents existed in machine-readable form, and a long process of scanning/OCR began. A substantial body of material was converted and mounted by the time CoOL's gopher facet was announced (Apr 1994)

Jul 1993 WAAC Newsletter added to CoOL

Volumes 9-18 were OCR'd, and mounted as plain text. The database was backfilled with earlier and later volumes over time.

Nov 1993 PhotoHst archives added
Apr 1994 CoOL Gopher added

Gopher service ran in tandem with WAIS service.

May 1994 First AIC documents added to CoOL.

AIC Ethics and Standards Committee supplements on propose revisions to the Code of Ethics and Guidelines for Practice and all of the committee's columns in the AIC Newsletter for 1993-94 were added. I believe this was the first AIC presence in CoOL.

Jun 1994 CoOL Web server announced

At this point CoOL operated as a triad WAIS, Gopher, and Web servers running simultaneously. The three "facets" covered distinct, but overlapping, portions of the document space. Among the first "web-only" documents was an electronic hypertext edition of Bookbinding and the Conservation of Books: A Descriptive Terminology, by Matt Roberts and Don Etherington, an out-of-print Library of Congress publication. This document is still onel of the most popular items in CoOL.

Simultaneously with the rollout of the web server, operation of the Cons FileList was terminated.

Oct 21, 1994 CoOL listed in Scout Report
Jan 1996 Gopher and WAIS facets phased out

NB:In January 1996, the Gopher and WAIS facets, having become largely redundant, were phased out, leaving only the WWW facet, with WAIS (and other search engines) used as back-end tools (i.e. WAIS is still used behind the scenes but the databases will be removed from the central server-of-servers and it will no longer be possible to access them directly with a WAIS client; it will be necessary to use CoOL's various search pages). The change was announced in the DistList with the following note:

I'm not happy about this decision as there are still a lot of people using gopher, but CoOL operates with no budget, and I can no longer afford the luxury of maintaining duplicated servers; it is too much of a drain on my time for too little benefit.

Since anyone who can run a gopher client can run a web client; since the major commercial services all offer web access now; and since there are public dial-in Lynx sites for those with only terminal access to the Net, nobody should be permanently disfranchised by this move. There is even an email interface to the web; for info send a 1-line message saying HELP to (this server sends documents up to 64k, text only, no graphics).

Apr 1996 CoOL becomes first North American Mirror site for the International Council of Museums (ICOM)

ICOM's central Internet server is located in Stockholm, Sweden. Due to limitations in the availability and speed of international communication links, ICOM plans to establish a number of mirrors of the primary site at various locations worldwide. Users will then have the option of connecting to the most conveniently located site.

The first of these mirrors is now in operation as a part of the Conservation OnLine service provided by the Stanford University Libraries in California. The technical problems involved in establishing procedures for the regular automated transfer of data to this site were solved by Walter Henry, the maintainer of Conservation OnLine. Thanks to his efforts the task of establishing further mirror sites will be substantially easier.

Jun 26, 1996 The Gopher facet of CoOL ceased operation completely
Jan 20, 1997 CoOL selected as a NetGuide Gold Site. "NetGuide has screened over 100,000 URLs and reviewed more than 50,000 sites and our Gold Award goes to only 15,000 of the Web's best sites.
Jan 21 1997 CoOL awarded LookSmart's Editor's Choice Award. "This award conveys the highest standard for providing a useful and high quality website.... LookSmart, unlike other directories that simply index the web and include anybody that asks, has editorial standards for inclusion in the LookSmart Directory. We have viewed literally over a million websites to select the 110,000+ chosen to meet our standards."
Oct 1 1997 Washington Conservation Guild (WCG) added. (Announced in Cons DistList on Nov, 1997)
Nov 1997 Internationale Arbeitsgemeinschaft der Archiv-, Bibliotheks- und Graphikrestauratoren (IADA) (International Association of Conservators of Archival Material, Books and Graphic Art on Paper) added.

From inception, this area contained both English and German text.

Dec 1997 United Kingdom Institute for Conservation of Historic and Artistic Works (UKIC) mirror added
Mar 1998 Institute of Paper Conservation (IPC) added
Sep 1998 Chicago Area Conservation Group (CACG) added

The Chicago Area Conservation Group is pleased to announce it's first Web Site. The site hosts a Directory of CACG members and their conservation specialties, an archive of past Newsletters, hyperlinks to other conservation related sites as well to the major Chicago Museums, plus, a sampling of the events hosted by CACG during our 1997/1998 season. We invite you to visit the site at: <> or to link directly to the site by clicking on the CACG icon on the CoOL welcome. I would like to thank Stanford University Libraries for hosting the CoOL and our site.

Jun 2000 Recognizing that, as a Stanford library resource, some complete bibliographic entities (monographs and complete serial runs) ought to be accessible from the <> SUL/AIR library catalog, our cataloging department adds records for two serial runs (WAAC Newsletter and JCMS. At the same time, it makes links from existing catalog records for two monographs (which the library holds in print form): Matt T. Roberts and Don Etherington, Bookbinding and the Conservation of books: A Dictionary of Descriptive Terminology, and James. R. Clifton, Stone Consolidating Materials: A Status Report. Additional title of complete monograph and serial run will be added as they are added to CoOL.
Sep 2000 PhotoHist archives in CoOL terminated

CoOL's PhotoHst archives were in operation between November 1993 and September 2000, with coverage from Sep 1, 1992 (beginning of PhotoHst) through Dec, 1999. In early 2000, began hosting PhotoHst archives at and offered better service to PhotoHst readers than CoOL had provided—subscription maintanence in addition to searching and browsing. With the availability of the ASU services, CoOL's archives no longer seemed necessary, and there were some substantive issues that positively motivated the cessation of our service. By agreement between Richard Pearce-Moses and Walter Henry, the archives in CoOL were terminated. See below for further discussion of the reasons for this decision.

History: Conservation OnLine provided access these archives first via WAIS, then via Gopher, and finally via WWW. In both cases, access was search-only, and used WAIS as the search engine. From references in the text it appears that CoOL began offering access to PhotoHst (via WAIS database cool-photohst at, port 210) Nov 1993. In Jan 1994, the address changed from aldus to The switch from Gopher to Web happened in April, 1996 and the initial URL was (later <>.

The cessation of the PhotoHst archives is covered in the following email message (the message from Walter Henry initiated the discussion, is quoted in full by RPM. It was dated Thu Aug 17 12:26:43 2000)

Albumen: Albumen Photographs: History, Science and Preservation added to CoOL. For more information on the project, see About the site.

Although intended from conception to be an integral component of CoOL, Albumen, like the California Preservation Clearinghouse, has its own web server and domain name. This pattern is likely to become more common as CoOL evolves. I am working on methods to integrate metadata from remote 'participant' sites into a kind of union catalog in CoOL, and at the same time am experimenting with a search engine that will allow us to do full-text indexing on resources housed at remote sites. Consider this the first small steps in the evolution of CoOL from a central repository to a union catalog/portal to a set of content-related but physically distributed resources

Started as a germ of an idea back in 1987 (on a real, live bulletin board, as opposed to an electronic one), Conservation Online (CoOL) has been providing online resources for conservation professionals since 1993. As its website announces, it is a "full text library of conservation information," covering a wide array of topics ranging from digital imaging to reprographics, and quite a bit of material in between. By clicking on any given topic, visitors will receive a brief overview of the subject, its terminology, and then a list of general online resources for consideration. Another nice feature of the site is the mailing list archive, which contain the archives of various queries submitted to different professional conservation groups, such as the Association of Moving Image Archivists, the Textiles Conservation Discussion List, and the Conservation Framer's Mailing List. The site is rounded out by a timeline that traces the CoOL's history from the summer of 1987 to July 2003. [KMG]

AIC has moved to a new host where you will find greatly expanded offerings for both conservation (and allied) professionals, the public, and members. AIC members will be especially happy to know that they will now benefit from member-oriented services well beyond those that CoOL has been able to provide.

CoOL and AIC continue to work together to provide quality information for the conservation community. AIC and CoOL have had a long, and happy history together—the first AIC documents were added to CoOL in May 1994, when CoOL was still a Gopher and WAIS site-- and I'm very pleased to say that much of the content you're used to seeing here will continue to be available in CoOL.

  On Jun 11, 2009 (Cons DistList instance 23:6), Cath Tierney reports the end of Stanford's support for CoOL and the DistList

Because of extraordinarily severe budget cuts resulting from the current economic situation's effect on Stanford's endowment, Stanford University Libraries and Academic Information Resources must eliminate many programs in order to continue to support the teaching and research mission of the University. Among these programs are Conservation OnLine (CoOL) and the Conservation DistList. A final instance of the ConsDir contained entries for 9696 people from at least 91 countries.

Date: 10 Jun 2009
From: Catherine Tierney <>
Subject: CoOL and the Conservation DistList

Dear Colleagues,

This is a difficult posting to write. For twenty two years, it has been Stanford University Libraries' great pleasure to serve and support the conservation community by hosting Conservation OnLine. Sadly, Stanford---like so many other institutions---has been hurt by the economy. As a result, we have had to make difficult choices. It is with deep regret that I inform you that we are no longer able to support CoOL. We feel it is important to alert you to this change as we are aware that so many of you rely on the distribution list as a medium of communication; there are still a number of things to be worked out.

Catherine Tierney
Associate University Librarian for Technical Services
Stanford University Libraries and Academic Information Resources

Walter Henry adds

It has been a great pleasure and privilege to work with this community and I look forward to finding ways to continue to do so. I've always held that conservation professionals were, as a class, unusually committed to the cause they serve; we really do care deeply about the cultural materials we are lucky enough to work with, and that care takes form in a remarkable dedication to the profession, to the ethical foundations upon which it is built, and to the community of practitioners from whatever discipline or specialty.

So, at the beginning of what would have been the DistList's twenty third year it is with great sadness, but also with some sense of pride, that I finally give up this enterprise and that of Conservation OnLine as a whole. I don't know exactly what will happen to the resources here but I have every faith that their fate will be in good hands.

I would like to thank, with all sincerity, Stanford University Libraries and Academic Information Resources, my own department, the systems and IT staff, and most of all the directorate, who have been unfalteringly supportive of my work all these years, and I know would continue to be so were the world in just a little better shape than it is now.

As DistList tradition demands, I leave you a final accounting: As of this day, the Conservation DistList comprises 9696 people from at least 91 countries. Conservation OnLine contains, at a very rough guess, 120,000 documents, possibly quite a few more. I hope they have been useful to you all, and I hope to be of service to you as we move into the future.


Some responses to announcement

  Eight days after the announcement from Stanford, on June 19 2009 (Cons DistList instance 23:6), the Foundation of the American Institute for Conservation (FAIC) assumes responsibility for CoOL and the DistList:

CoOL is Coming to AIC!

Having reviewed a proposal from AIC and following several discussions, Stanford University Libraries has agreed that AIC will be given responsibility for CoOL and the Conservation DistList. The transfer of content from the Stanford servers will take place immediately with expert guidance from Walter Henry, John Burke, and technicians at Stanford.

Our first goal is to have the DistList operational as soon as possible. Watch for one or more announcements on the DistList for periodic updates regarding the resumption of activity. Other CoOL resources will come online under new URLs as expeditiously as possible. Discussions with allied and affiliate organizations will continue.

AIC is pleased to be entrusted with these invaluable resources and for the opportunity to sustain and develop them into the future. Our goal is to keep CoOL and the DistList safe, viable, objective, and accessible for the conservation community worldwide.

  -- AIC Executive Director Eryl Wentworth and the AIC Board of Directors

Walter Henry continues working on both projects.

"Kudos to CoOL
Posted on Jan 11, 2013

The Washington Conservation Guild would like to extend heartfelt thanks Conservation OnLine (CoOL) and to Walter Henry, CoOL's guiding light, for welcoming WCG to the web way back in October, 1997. For over fifteen years, CoOL hosted our website at no cost to the Guild, providing server space and encouragement first at Stanford University, then through the Foundation of the American Institute for Conservation of Historic and Artistic Works (FAIC). WCGs website has gone through several transitions of its own in that time: Mark Knight, the site's designer and first "Web guru" stepped down in 2003; in 2008, his successor, Erin Blake, worked with web designer Jill Kianka of Vico Rock Media on the site's first re-design. The website has now been re-re-designed by Jill, and moved to a web-based content management system on an independent server on January 9, 2013. While this site is no longer formally connected with CoOL, the Washington Conservation Guild (like everyone who cares about the conservation of historic art and artifacts) remains a dedicated fan. Thank you Walter Henry, CoOL, and FAIC, for all you have done, and continue to do."

Presentation about CoOL

If you are the sort of person that enjoys outlines, here are some "slides" for an informal talk about CoOL given in house talk about CoOL, in May 1994. See also the text for an AIC talk that I gave in June, 1994, which touches at least a bit on CoOL, the DistList, and it's place in the information environment of the conservation professional

The Conservation DistList Archives

The Conservation DistList, which was the core material for CoOL when it began, still serves as the heart of the server. The following text was written in answer to a question about the archival policies of the list, but provides a bit of an overview of the server as well. Other bits of information about the DistList policies, etc., are contained in the welcome material that people receive when they sign onto the Cons DistList

Yes there is an archives—Conservation OnLine (CoOL)—where depending on the access method you use (WWW, a superset of the others, being optimal), you can retrieve the DistList traffic in several ways.

(This list is cumulative; each method has all the capabilities of the other), and all the authority controls remain the same:

WAIS: Full text searching for individual messages (i.e. Analytics). Messages are returned in order of (as far as WAIS can manage) relevance to your query. The messages are rigged to favour Authors name, Subject, and Date. Note that all are subject to some simple authority control. I maintain a name authority list (not perfect, but pretty good), and a more casual subject authority list (it's based on the subject that I assigned to similar messages in the past, with occasional recourse to the Art and Architecture Thesaurus). Dates are also forced into a consistent format.

Gopher: Analytics are searchable as above, plus:
Complete digests are browsable, arranged by date. (in this form you get exactly the same thing you get when you receive the DistList as a subscriber/participant).

World Wide Web: provides access to the gopher (hence all of the above) plus:
HTML representations of individual messages are browsable, organized by Author, Subject, and Date. (I may add wais indexing (or some other fulltext indexing/retrieval) at this level, but haven't decided yet).

Every individual message is available (with the exception of messages from the first few months of 1987 when this was just starting and we hadn't started taking it seriously). In the early days, the format was quite different (at the start it wasnt a moderated digest). If I recall, I created a fake 'Volume 1' to hold all the early messages but it doesnt represent the actual form in which the messages went out at the time.

As a moderated (heck, it's edited really) digest, the DistList (and it's archives) are subject to some very un-archival manipulations. For example, sometimes I'll retrospectively normalize the spelling of an important term (or normalize a subject field) to enhance the searcher's chances for finding what s/he wants. In this sense, this isn't an archive, but a database (I call it an archive only in the degraded 'nerdish' sense of the term.)

As for retention, I have a personal commitment to retain the messages (albeit with the interventions described above), permanently (whatever "permanent" means). There are two reasons for this. First, conservators and conservation scientists often need to know what was thought about/done to objects in the past, so knowing about a treatment common in 1990 that is obsolete in 2020, can have a real impact on conservation decisions. Second, and this doesn't apply just to the DistList but to mailing lists, Usenet etc, I believe that resources like this one will provide future historians (esp cultural historians) important evidence about what is beginning to look like an important historical period. Knowing how we talked to eachother (Usenet is a particularly revealing artifact in this regard), what conventions of discourse, what kinds of information we chose to convey and how casually or formally—and how quickly—we chose to write it, should make for interesting study in a hundred years or so.

Though it's not widely known, the DistList is actually an SGML application. It's all marked up to a very simple DTD, which I believe will give it some chance of surviving through the next few revolutions of the network wheel. I also have a notion to try but haven't broached the subject with the archives folks yet, to get our Dept of Special Collections and Archives to accept a permanent-paper version (yes, despite my own interest in preservation of electronic materials, I maintain considerable skepticism about the ability of a resource to survive repeated cycles of human decisions about migration, having seen too many things abandoned casually when migration costs or current priorities aren't in synch with the long-term preservation mission). At Stanford, we are just beginning to formulate a collections development policy for electronic materials, and I will, naturally, suggest the DistList and CoOL be officially 'acquired' for the collections.

About the logos

The earliest set of CoOL logos were designed by conservator Erich Jacobs. There are a number of versions and a different one is selected randomly everytime you (re)load the main page. I've added a few of my own, including the principle blue square

CoOL Statistics

Use statistics were at one time available, (though I can't imagine why anyone but me would have been interested in them). Note that they are often out of date, as I don't run the stats often, so pay attention to the dates and if you see improbable stats, (e.g. very low number of hits) try again in a week or two. After CoOL left Stanford such statistics were no longer gathered.

Software and Hardware

Since AIC took on responsibility for CoOL, the server has been running on a Slackware Linux system, x86_64 Intel(R) Xeon(TM) CPU 3.40GHz

At Stanford CoOL ran on an IBM RS6000 under AIX. Originally the server software was NCSA's httpd. In 1995 this was replaced with Netscape Communication Server 1.0 and in July 1997 this was replaced with Netscape Enterprise Server 2.01.
