Sage combination advice.

"Combining" is at the center of LibraryThing, and one of the most important things members do. Members can combine, separate, split and "never" books, authors, tags and LibraryThing Local venues. A whole subculture works to make sure things are in order, and "connected right."

Spam Catching!

LibraryThing is anti-spam, and members keep us that way. An entire group is develoted to finding obvious spam and debating less certain examples.
