When I see kitchens in decorating/remodeling magazines, I just laugh at the "bookshelf" which usually holds five or ten cookbooks. I had lower cabinets built in in the kitchen which hold about 200, and I keep the ones not as frequently used on shelves in another part of the house.
My last kitchen had a complete wall of shelves from floor to ceiling that were *supposed* to be open shelving to show off all one's pretty dishes and crystal, dontcha know? Ha! I still had to have extra shelves put around the breakfast table and a unit just inside the dining room, for the cookbooks.
I did have one of those "10-15 books" shelves in the kitchen of the house before that -- what a joke -- but a large morning room with lots of wall space under the windows for half-size shelf units saved me. (Collection was smaller then, too.)
Finally had to decide that Christmas cookbooks could go on the highest-up shelves near the ceiling (I'm very short), so it would be a once-a-year (ha!) chore to retrieve them.
