Alright let's have 'em.
Here's mine, most were bought used for around $5-15.
Comments? Suggestions? Jealousies?
Some standouts for me are... From My Chateau Kitchen by Anne Willan, all the James Peterson books, All About Braising, Julie Sahni's books, Moosewood Daily Specials is awesome (what are the other good Moosewood books? Sundays is a new one for me, only made a soup from it so far), Ajanta..
Techniques of Heatlhy Cooking taught me a ton about food and cooking in general.
Oh and most useless books... Lobel's a bit because I can't afford to eat like that, Silver Spoon didn't like it much, Cooks Catalogue is a bit of a headscratcher I guess. Good to see what you might be missing in the kitchen though.
