Nope, not at all. Although on LibraryThing I recently recall seeing some sort of table at the bottom of some works I have searched. Looking up Conceit by Mary Novik, I see the text "The first test round has been closed. Visit the Open Shelves Classification group for details." I have not classified any books yet but I would love to do so!! I am totally strict about organization, my desk, my home, bookshelves, computer files. I use Bookpedia to catologue all my books and I classify some areas of my bookshelves.
In University I took Library Science 2000, a very cool class...and we had to learn all about classification, referencing and the Dewey Decimal system...sometimes I get bugged at work for this. :)
I wish I had known about this feature earlier...ostrich syndrom I guess. I have joined the group so I can be involved in future endeavors.
