The CP/M Library (.LBR) file format was created by Gary P. Novosielski. It is a multi-file archive commonly used on CP/M operating systems in the early 1980s.

This web app shows you the contents of a Library file and lets you extract the files. At this time it only works with uncompressed .LBR files. It does not work with .LQR (Squeezed) nor .LZR (Crunched) files.
