In our old house there were books on bookshelves everywhere... the spare room was a library with a bed in it. The cottage, however, has not a single bookshelf. My cookbook collection is sacrosanct, they were never up for discussion. As for the rest, after a great deal of sorting (weeping and wailing) and tactical giving away, I have my core collection: stored (the "must haves") in one of the pair of Chinese Wedding Baskets that doubles up as a coffee table, boxes in the attic and, as I discovered the other day (a secret stash of vegetable growing and poultry care guides) in the second drawer down of the sideboard!
And in case you're wondering where I might my new purchases... remember the post-Christmas clear out of the tape and CD collection? It's amazing how much space they took up; I can probably get a good three dozen books in that chest instead!
