Digital Library Center: Layered Media Preservation

Standards for digital preservation of interactive and performance digital media are available from texts on preservation, and the following is adapted from Erich J. Kesse's "Strategies for Microfilming Scrapbooks and Layered Objects" in RLG Archives Microfilming Manual.

Scrapbooks, diaries, and unconventional book structures often contain pages with layered or dimensional objects. Such pages include parts which display one of the following characteristics:

Overlapping parts (e.g., page layered with memorabilia).
Enveloped parts (e.g., a diary containing letters in pasted-down envelopes).
Folded or hinged parts (e.g., a page containing folded newspaper clippings).
Movable or pop-up parts (e.g., an "artist's book" or a child's pop-up book).

Steps for Digitizing:

First, film an image of the page as found, with all facets or openings on the page closed.
Then, film each facet of each item in logical sequence for reading order (so this should vary as applicable): left to right and top to bottom.
Within this order, overlaying items should be filmed before underlaying items, and envelopes should be filmed prior to filming their contents.
Every facet of an item should be filmed before the filming of another item begins, and every item on a page should be filmed before the filming of another page begins.
If a layered or dimensional item can be safely detached, remove it and film it separately from the page on which it is found. Otherwise, a blank sheet of ivory or black paper can be laid behind the individual item to mask it from the rest of the page.

Resources

The Jackson Henson MacDonald Scrapbook and the Visionaires Scrapbook (1938-1948) are examples of basic scrapbooks - no movable parts, all images on pages, and no separation of the parts of the images on the pages instead having only the pages with images scanned.
The Bardin Scrapbook is a slightly more indepth example because each scrapbook page scanned, followed by high resolution scans of each of the individual images on the pages.
