As the new book buyer, one of my responsibilities is to talk to self-published authors who want Green Apple to stock their book. If you ask buyers from other stores, I think you'll find that this is one of the least favorite parts of their job: having to deal with some pushy, self-promoting author who drops in without an appointment and expects you to stop whatever you're doing to meet with them.
I'll admit, I sometimes grumble when I get paged to the front counter for this purpose. And if I'm in an appointment, I'll give them The Heisman (i.e. politely ask them to come back at a better time).
However, I know that it is important for me to be open to these interactions for several reasons. For one, independent bookstores, I feel, have an obligation to stock books from local authors, assuming the books are reasonably well-produced and have some potential for selling. Two, pushy and self-promoting is the only way to get it done if you want to get your book into a store. And three, it's amazing how often I am pleasantly surprised by the author and/or their book.
The most recent example is when Rauf Naqishbendi dropped in to see if I would carry his book "The Garden of the Poets." Rauf is from Halabja, in Kurdistan, which was famously the victim of a chemical gas attack by Saddam Hussein in 1988, killing 5000 inhabitants. Here is a review of the book. I haven't read it, but it just makes you wonder at the people who walk into your store, and what stories they have to tell. This is one of them. Here are a few more.
Camp Quest has one of the worst covers, but two of the nicest authors I've ever met. Written by two former San Francisco teachers, it is set in a fictionalized Bay area locale during the years 1984-2028, and is about a science teacher who invents a drug that turns gifted but underachieving adolescents into dedicated students (what teachers fantasize about in their spare time, no doubt). The Shankels must have a lot of dedicated former students, because we've sold 36 copies so far.

A final word to all you self-published authors who are going to rush to the store- we are pretty strict about only carrying books by local authors, i.e. living on the west side of the city. And the books have to have a spine. And please call and make an appointment before coming by.
