What kind of self-stick (pressure-sensitive) call number labels are safe to use?

The Library of Congress has developed specifications for pressure-sensitive call number labels that can be affixed to book spines and to book boxes.

Two alternatives to applying pressure-sensitive call number labels directly to book spines are:

  • Box the book and affix the label to the box
  • Place a 2" wide cardstock tab (length of tab is 3/8" taller than length of book cover) inside the front cover, with the call number at the top of the tab so it's legible when the book is on the shelf

DO NOT use sticky notes on collections, collection folders, or boxes, the adhesive is not intended for long-term use and the adhesive can migrate and stain collection items.
