I dunno - 400 to 500 I suppose. I haven’t counted in years. I used to think it was a lot, but now I’m starting to wonder.
Oh yes - no cookbooks. The only one that would do me any good starts with “open the can, making sure not to cut yourself.”
I think my family collectively owns several thousand.
I took about 70 to school with me. Choosing was so hard…
My best friend’s dad is a librarian. He is considered an expert on science fiction. Their house is books. It’s in the ten thousands. I want to live there.
1000 COOKING BOOKS? WTF?
Dude, are you a chef or something? That is positively astounding to me, especially since, cooking-wise at least, I am your antithesis. I have never even read ONE single recipe. Well, one actually. Do brownies count? 
1500 (Estimated)
of these aprox. 400 are cookbooks
at least half the rest are non-fiction
Mrs. Bandersnatch is forever after me to get rid of some. I am always thinking of ways to distract her off this task.
