Rare Book Identa-Strips

University Products' acid-free and lignin-free Identa-Strips provide easy identification of shelved rare books. A die-cut tab prevents slippage into the book when vertically shelved. these acid-free Identa-Strips won't discolor pages of books into which they are inserted. Tab is located 6 typewriter spaces (1'') from top. A no-tab version is also offered. Price per package of 100. * Note: We recommend the non-tab Indenta-Strips for those books with very brittle pages.
