Bug Collectors

This is the place to post or discuss bugs on LibraryThing (this includes TinyCat). It's not a wishlist for features, nor a list of things that could be better.


  • The Bug Tracking page can be reached here

  • You can see a list of the various bug statuses and how they are used here.

  • Join or watch this group to see "Bug Tracking" on the sidebar of your Talk pages.


This group was created in 2006 by CupCakeMonster. In October 2010, it was taken over by LibraryThing staff, to add new information, options and a group picture.
