O.K. .....I am new and for the life of me cannot figure out what TBR pile is.  Please clarify?

:-) That's your To Be Read list.

Here is a glossary of terms used here.

http://www.paperbackswap.com/help/search.php?terms=glossary

TBR = To Be Read.  Books are automatically added to this list once you receive them (unless you uncheck that box that says "Add this to your TBR pile?" when you mark the book received).  It's just a way for you to keep track of the books you haven't read.

You can also add books that you got from somewhere else besides PBS so you have a record of all your TBR books not just the ones from here. It tells you if your version is WLed and if its on AR/

OH BTW BTW means by the way

PBS is paperbackswap

TBR is to be read

WL is wish list

AR is autorequested

Thanks for the info!!
