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
