I’ve been slowly alphabetizing my books and discovered there are a few books I own three copies of.
1. Voyage in the Dark, by Jean Rhys
2. The White Album, by Joan Didion
3. The Bloody Chamber, by Angela Carter
I did go through a phase where I was buying copies of books I had in storage. I was living in many sublets, and missed my books. But I apparently didn’t sell any of the duplicates, and then went on to keep purchasing them, as if I both couldn’t forget them and couldn’t remember if I still had a copy at home. The White Album I own in paperback and mass market paperback, but I have three identical copies of the Bloody Chamber in paperback, plus a fourth, high-end Folio Society edition of it (that is stunning–everyone should get this). And two of my Voyage in the Dark copies are the same edition as well.
Also, I can’t sell any of them. I tried to put some in the sell pile and then couldn’t. I have no idea why I have this attachment.
I’ve been away from this blog a long time, I know. I’m back to regular updates here. See you again soon.

At the Baltimore Book Thing, you can drop off any books or magazines you no longer want. They also provide free books for anyone who wants them. It is a wonderful way to pass on books you no longer want or need, and it’s less guilt producing to pass on the duplicates you have an inexplicable attachment to. When I inventoried my books years ago, I found duplicates as well. It took a few years before I could release the to the Book Thing.
