The verdict is in on Post-it NotesŪ and similar adhesive markers! Though they are easy to use and may be removed from most paper surfaces, DON'T be tempted to use them in books. These seemingly harmless "markers" leave behind their adhesive, even when removed immediately. The adhesive hardens and leaves a film that becomes acidic. This results in eventual discoloration and brittleness of the paper. They were designed for short-term application to expendable documents and have no place being used on permanent records and books.
The National Archives and Records Administration (NARA) conducted research which determined that even when removed immediately, the adhesive residue remained. Even more dramatic effects result when used on newsprint (some of the ink is removed) or on brittle, fragile paper where removal may result in tearing the page. The NARA report concluded that these notes will cause increasing preservation problems when used with permanent records and should be avoided.
The UCSD Libraries have the right to charge for materials returned with adhesive markers and any damage caused by their use. Signage reminds patrons not to use these in library materials. The Effect of Post-itsŪ bookmark is available at the circulation desk for patrons to take with them.
