What this presentation covers
Part 1: Why materials deteriorate.
Part 2: Shelving materials carefully.
Part 3: Handling materials carefully.
Part 4: Identifying and preventing damage.
• Put only necessary papers in books during processing.
• Don’t put anything heavy on a book with a lot of papers in it.
• The book may split or a cover may break off.
Paper can cause damage.
• Remove all paper when processing is completed.
• Acidic old paper turns yellow and can stain the book.
Avoid paperclips and post-its.
• During processing, insert papers into the book with the top edge sticking out.
• Don’t use paper clips, scotch tape, or post-its.
Post-it notes
• Can tear fragile paper.
• Can pull the type off the page.
• Leave their stickiness on the paper to collect dirt.
• NEVER put Post-It notes on books, and be careful removing them if you find them.
Paperclips
• Should NEVER be used on books.
• Can rust and stain paper.
• Can tear the pages.
• If you find any, remove them carefully.
Use red or white cotton string
• To hold books together, or to keep papers with them.
• Tie bows, NOT knots.
• Or put the item in a campus envelope.
Date due slips The pressure of stamping pushes on the cover and encourages
the hinges
to tear and
finally
break.
Date due slips
Always put the date due slip on the textblock side of the book, not the cover side, so that the textblock can absorb the pressure.
Date due slips
If the date due slip is already on the cover side, put the book down so that the cover is flat on the counter while you stamp. Do the same when wanding barcodes.
Cleanliness
• Extremely important in preventing mice and insects.
• If you see insects or mice in the stacks, tell your supervisor.
• If you find insects in a book, try to wrap the book up with the insect inside and give it to Preservation.
Microfilm and microfiche
• Cleanliness is important.
• Oil from fingers can eventually destroy the images.
• Wear white cotton gloves when handling film.
• Handle rolls of film only by the edges, and microfiche by the headers.
Microfilm and microfiche readers
• Keep the equipment clean and well maintained.
• Dirt on the lenses can scratch film, and if the equipment is operating poorly it can cause tears
Videos, CDs, etc.
• Keep them away from dirt, water, and magnetic fields.
• Keep equipment clean and working well.
