As someone who spends most of her time in either (a) the kitchen or (b) the library, I experience a great deal of joy when the two intersect. One of my colleagues introduced me to Any New Books? and my life has never been the same.
Using the site, you can set up preferences to receive weekly emails about the latest and greatest titles in that subject area. I have my account set up to receive boat-loads of alerts, but my favorites are in Cooking, Food, & Wine and Health, Mind, & Body. I've found some great cookbooks in these weekly emails, and definitely recommend them for anybody who loves books and cooking!
