I have approximately 677 books in my apartment.
I didn't count simple hardware manuals, and multiple issues of a comic book were counted as one book. Though I did count all the various bound role playing game books. I also only bothered to count once, and so some books were missed and some were counted twice. Nor did I count electronic books.
Maybe one day I'll pretend I'm a library and create an electronic database listing all the titles so I could have a more accurate count.
I decided to do this because the new years party I went to last night was hosted by a woman whose doing her radiology internship and she only had one small bookshelf that wasn't even full. And that's after an education that requires some level of intense study.
It seems odd to me that an educated person doesn't have large piles of books.
