Preservation of artifactual value in microfilming projects

When we microfilm volumes with photos or illustrations that the selector
wishes to retain in hard copy format in addition to filming them, we use
a target which states "The original illustrations from this microfilmed
book are located in___________" (the particular location is listed).
When the microfilm returns from the vendor, the film and the original
are sent to the Catalog Dept.  The film is cataloged with the note
"illustrations are located in the ____________ library".  The
illustrations and the title page are removed from the original volume,
deacidified, repaired as needed, put in a protective enclosure or acid
free envelope, depending upon the number of items.  The film number is
placed on this container, sent to the particular location, and available
to users upon surrender of their ID.

When the original is to be photocopied and the selector wishes to retain
the photos/illustrations, they are removed, sent to the Conservation Lab
to be deacidified, and encapsulated.  When the encapsulated pages are
inserted in the correct place in the photocopied book, a blank sheet is
placed between the encapsulated page and the photocopied pages; the
pages are trimmed, the photocopied volume with the encapsulated pages is
cataloged, and then sent to the commercial binder for binding.
