Re: [ARSCLIST] Cataloging sound recordings

["Steven C. Barr" <stevenc@xxxxxxxxxxxxxx>]

The Library of Congress has extensive information on the MARC system/format
at
http://www.loc.gov/marc/ which I found very interesting.

As near as I can tell, MARC seems to be a data file format something similar
to HTML. Instead of designating items with paired tags, MARC seems to
precede
items with numberic field identifiers, and each field has a fixed length as
well as being set off by firld terminators. Most of the fields are defined
in the format; as well, the format is clearly intended for the catalguing
of printed items.

I would assume the result is a file which lends itself to being displayed
on a terminal or used to print index cards (in neither case will the numeric
designator be included). In this sense, it is similar to a Table in HTML,
which uses <TR></TR> tags to identify rows (data records) and <TD></TD>
to identify Table Items (data fields).

The good thing about this is the fact it would be very simple to create a
working user interface using Visual Basic (possibly also Visual C++ but I'm
not fluent in that) which would create a text file. This file would include
the identifiers and terminators for each field, and read the inputted text
from user-completed text boxes for insertion into the file. As well, it
should be possible to read the data from the file using (and searching for)
field identifiers and terminators, and then insert that data into MS Access
or other data tables.

The bad thing is that using MARC to catalog sound recordings would be akin
to trying to license computers using the softare already in place for
motor vehicle licenses!

For example, here is a sample phonorecord entry from the LOC site:

The same record with MARC 21 content designators:
