I used to go crazy with buying paper books to a point where my library was overflowing with books, and then I moved in with my fiance, who is a teacher... she had about three times more books, notes, binders and other paper material... We're still in the process of trying to find room for a new library to fit everything. But needless to say, that really stopped my book buying spree. Until I got an e-reader.
With books no longer taking up space, it's back! A few days over a month and I've got about 20 new books. Managed to finish 5, but I really need to stop looking at the stores as I've already got 15 more books I bought, plus another 50-60 free ones to finish...
