This is a group to post your "lists" -- bibliographies.
* "top ten feminist science fiction novels" * "must-have reference about Garibaldi & the red shirts" * "best mysteries based on science"
Etc. (We have a LISTS feature on LibraryThing now -- https://www.librarything.com/home#lists -- which lets list creators specify whether the lists are by them, or commonly editable, and private or public.)
The emphasis is on posting all those lists you might otherwise post to Amazon.com or wherever.
