I went to the fun Art Book Swap organized by Regency Arts Press last week and held at the Museum of Modern Art. This is the third book swap that the organization, directed by Lauren Wittels, has produced. Here's how it worked: you bring any art books that you don't want or need anymore, hardcover or paperback (but no magazines or how-to books), present them at the check-in table where you get a receipt indicating the number of books you have donated, and then browse the tables full of books donated by other swappers and by publishers and dealers . There were more books filling the tables all day long as swappers arrived and donated. At the end of the day all remaining books are donated to prison libraries through local organizations: in New York the Prisoners' Reading Encouragement Project, and in Los Angeles the Bunche Center Prison Outreach Program. I walked out with some amazing books!
