I tend to read a lot of books - maybe 3-4 a week, but I get them from the library. I only buy maybe 2-3 books a year and these are ones that are favourites. I reread all my books on a regular basis.
DH is not a great reader (of books, he tends to read magazines or stuff off the web) but whenever he sees a book he thinks he might enjoy he buys it. He tends to buy 3-4 books a month. But only reads about 1 book a month. Now I have no problem with him buying books (though I find his aversion to the library odd) but ... we have limited storage space in the house.
His "to be read" pile of books is under his bedside cabinet and piled up next to it. It is fast encroaching on bedroom space. His "read" books are on one of our 3 bookshelves. Herein lies the problem - the bookshelves were full about 5 years ago when I first suggested that he might like to sort out some to get rid of. They are now double stacked and even then we are starting to run out of space. DH has kept every book he has ever bought (as far as I can see) and never reads a book again once he has read it once. I regularly get rid of ones that I won't reread so the books that I own are well thumbed favourites which are often reread.
I ever so often "suggest" he gets rid of some as we're running out of space. Hasn't happened yet. There's only so much sorting of my own that I can do. I'm getting increasingly fed up that I am the reader and yet my books are swamped by DH's (who has some that he read before I met him 14 years and has never touched since).
I don't have a problem with having the books per se (though I think keeping books you never look at is a bit odd) but we just don't have the space for them (actually we could do with getting rid of one of the 3 bookcases we do have).
Don't feel I can get rid of them without DH's say so (tis his stuff after all) but fed up of putting up with having them everywhere!
