|Cataloging Practices Manual||[CPM-630]|
An item is judged to be unsuitable for regular processing due to brittleness under the following circumstances:
Cover and/or pages are damaged or becoming detached and are subject to crumbling. Note: Hardcover volumes whose covers and pages remain intact may be processed according to regular procedures despite brittleness.
Paper fails the corner fold test: turn to page 50 of the volumes, or the middle if there are fewer than 50 pages. If the page has text or illustrations that cover it entirely, go to the next page with a blank margin to perform the test. Using the forefinger and the thumb, fold in a small section of the lower right-hand corner of the page. Fold it flat against the page. This is one fold. Take the same corner and unfold it back to its original position. Then fold it flat the opposite way along the fold line. This is the second fold. Four folds should be made to measure the degree of brittleness. After the fourth fold, flatten the corner and give a light tug to see if it is still attached to the page.
Brittle items to be filmed and print discarded after filiming will be delivered by MAS to the Preservation Reformatting Department (PRD) in Room 101 to shelves labeled as "Brittle books from MAS".
Note: If a book in this category has a bibliographic record that is tracked to MAS, consult with Dave Motson in Database Maintenance to either suppress or delete the record.
