Writing guides, grammar books, punctuation how-tos... do you read them? Not read them? How many writing books, grammar books, dictionaries–-if any-–do you have in your library?
I can't say exactly how many since I don't have all my books cataloged in LibraryThing yet.
Let's see... I have style guides, Struck & White and Chicago (yes, I bought the new edition as soon as it came out) as well as APA (required for grad school) and MLA.
I also have dictionaries, lots of them. Bilingual dictionaries: French/English, Spanish/English, German/English, Modern Greek/English (I think we also have a Latin/English dictionary kicking around the apartment). I have a "collegiate" English dictionary (I think) sitting on my desk at home. I know I have at least one other in storage as I distinctly remember raiding my grandpa's bookcases. I have a wonderful, monstrous German dictionary that I got when I was working on my translation project and a lovely children's German dictionary with illustrations. I also have at least one thesaurus.
I do have a copy of Eats, Shoots and Leaves, but I've never gotten around to reading it. And, I know I have at least one other book like it, though the title is escaping me right now.
As for reading them... the reference books I use for reference. I also like using the OED online and dictionary.com/thesaurus.com for quick checks. I'm more interesting in reading about the history of them, like Simon Winchester's books on the development of the OED (particularly The Meaning of Everything).
