If you have any books you'd like to give away, consider donating them to the New Orleans Public Library. How? Check out this announcement (which I found on NYFA Interactive):
"The New Orleans Public Library is asking for any and all hardcover and paperback books for people of all ages in an effort to restock the shelves after Katrina. The staff will assess which titles will be designated for its collections. The rest will be distributed to destitute families or sold for library fundraising. Please send your books to:
Rica A. Trigs, Public Relations
New Orleans Public Library
219 Loyola Avenue
New Orleans, LA 70112
If you tell the post office that they are for the library in New Orleans, they will give you the library rate which is slightly less than the book rate."
