Many factors must be considered when preserving these unusual materials, and there are many special techniques available to successfully preserve them. This training is essential to ensure that pages are not skipped and that materials are filmed in the proper order and orientation. Using this technique, thick library-bound volumes with limited interior margins are frequently filmed successfully. Original bindings, such as vellum bindings, can be accommodated within protective book cradles. Newspapers Newspapers pose significant filming challenges.
Newsprint is often extremely brittle and oversized.
Bindings are very tight and the text is bound deep into the inner gutter of the volume. Illustrations and color must be filmed at appropriate densities to optimize information capture. When permitted by the client institution, Preservation Resources' staff employ a variety of disbinding methods that are minimally obtrusive and can save the maximum amount of text that was obscured in the binding process. A guillotine can also be used for disbinding with the permission of the client institution, but generally only as a method of last resort. Oversized Materials Foldouts bound in small books and large format materials such as maps and charts are often difficult to capture using standard book cradles or flat-bed camera stands.
