I learned to read before I entered kindergarten. (I actually remember when my mom found out, a couple of months after my fifth birthday. I read the small print off a jar of Kraft's Marshmallow Creme, much to her astonishment. She immediately called her best friend, who was a kindergarten teacher.) I have pretty much had my nose stuck in books ever since.
I was a fixture at local libraries when I was a kid (the Central Valley communities I grew up in didn't have much in the way of bookstores). Berkeley actually has a very fine public library system (despite the post-Prop 13 cuts) - check out the library's bookmarks for a whirlwind Web tour - but it also has 44 bookstores and most of them seem to be doing okay. My current favorite is Black Oak Books (used cookbooks and previously-owned Wodehouse, oh my), followed closely by Moe's, Cody's, and the downtown Barnes and Noble.
I've also been known to go crazy in bookstores when I travel and have to send the extra ones home via UPS. If you're in London, visit the Charing Cross Road and Foyle's; New York has The Strand, Shakespeare and Company, and a host of other fine stores. Portland has Powell's.
My tastes vary wildly, but if you want to see what I've been reading, or rereading lately, click here.
I used to have about five CDs to my name (mostly early music, which I liked before it became trendy). Now that I have a car with a 6-CD player, I have a few more. Berkeley is a great place to shop for this - the out-of-towners usually drool at the selection.
