Hello, everyone!  I am pretty new, and this is my first foray into the forum area.  I see many abbreviations being used, and do not know what they mean. Is there a sticky somewhere, explaining them?  Thank you.

Acronyms/Abbreviations common on PBS:

• ARC = Advanced Reader Copy (aka Uncorrected Proof, Review Copy); a preview copy of a book sent to reviewers in advance of a book's release; not the final copy of a book, and not permitted for swapping at PBS.
• BCE = Book Club Edition.  Book club editions are special printings of books that use cheaper materials and are slightly smaller in size than standard hardcovers. They're usually sent out via mail order book clubs, hence the name, and sometimes do not have ISBNS (if this is the case, they must be Posted using the Post a Book without an ISBN feature).  They are permitted for swapping at PBS.
• BIR = Books I've Read List. This is a list of all the books you have already read.
• BoB = Box-O-Books. This service allows members to swap books without credits! See What is Box-O-Books? for more information about this feature.

• RCs - Requestor Conditions

• TG - Tour Guide
• UnPosted books = books not currently available to order; these books may be added to your Wish List.
