Hello All,

I don't know if this helps but from Chapter 6, section 2 of the Federal
Depository Library Manual it states:

GPO produces and distributes diazo process microfiche, which are subject
to fading over time and should not be considered an archival document
storage medium. However, with proper care and storage, GPO microfiche
will have a long shelf life of 100 years or more.

It also mentions:

Never mix diazo, vesicular and silver halide microfiche in the same
drawers; preferably keep them in separate cabinets. Chemical reactions
between the various compositions may cause deterioration of the
microfiche.

It doesn't say how long they have been sending diazo process microfiche
but at least we know what type of fiche it is currently being
distributed.

Someone correct me if I am wrong, but wasn't there a time when
depositories received some silver halide fiche?  I remember at a
previous job that they were some GPO fiche that had been stamped silver
halide.  As I recall, depositories made an effort to get replacements.

Does this sound familiar?

Govdoc-l,

I just received a phone call from another library informing me that
microfiche are hazardous materials and need special disposition. The
University of North Carolina at Chapel Hill's environment, health and
safety web site lists them as hazardous and require recycling for the
silver content and stating that they should not be placed in the trash.

I hadn't heard heard this before and want to know what others are doing
to dispose of microfiche.
