I've never done a reading challenge, though there are lots to choose from floating around the internet, and sometimes they appeal to me, but there's one I'm actually thinking about doing in 2010. The Bibliophilic Books Challenge involves reading three, six, or twelve books about books and reading, fiction or not, during 2010. I absolutely love reading bookish books, so I imagine it will be entirely possible to complete this challenge. I'll aim for the lowest level, reading only three books, but if I read more so much the better.
The only book I have specifically in mind is Howards End is on the Landing, by Susan Hill. I'm sure everyone's already heard about this book, but if you haven't: it's nonfiction, about the author's decision to spend a year reading only the books already in her house. Otherwise, the field's wide open; I could read any number of things. I wouldn't be surprised if I read a novel about books without even thinking to apply it to the challenge.
Has anyone read any good bookish books they'd like to recommend? I don't have any particular ideas, so I'd better start compiling a list.
