"Most commonly shared books" category?

Hi all, I am the Chair of the Library Committee for the First Unitarian Universalist Church of Winnipeg. I just came across a printout of a Library Thing page for this group from November 2008. It showed a category called "Most Commonly Shared Books (Weighted)" which appears to be a list of the books that the members of the group have in common in their collections. Does anyone know if this kind of information is still available on Library Thing?
Many thanks,
Jeanne
