Do you ever weed out cookbooks and, if so, what do you do with them?

For years I never got rid of ANY books of ANY kind. Then I realized that made no sense - for me anyway. So I starting weeding fiction (rarely buy it; go to the library) and non. But my cookbooks seemed somehow off-limits. Then I weeded a whole lot of them. Let's face it, some really do get dated or I hadn't cooked from it in 10 years or I didn't like the results. Whatever. I donate books to the library but they don't want a lot of copies of the same book and some can't even accept donations because they're too short-staffed to process them. So I called a crisis center for women and children in my town and asked if they had any need for them. They jumped at them. Said that most of these women leave with the clothes on their backs (if suspected of leaving, they'll get beaten even more). They will be setting up homes again and cookbooks are frequently high on their list. I thought of this this morning while stacking books on top of the bookcase because the shelves are full. Thought I'd pass it along in case you're looking to re-home any books.
