You show me yours?
The books on the middle shelf and those stacked horizontal on the lower shelf are the ones that I use the most. The top shelf has books I don't want to throw out but use only occasionally. I love reading cookbooks and could easily spend heaps of money on them but I try and only buy those I know I'll use and fill a gap in my shelves ... figuratively speaking that it. Collection building you know.
I used to subscribe to Cuisine magazine and Dish. I liked Dish better, but the lack of an index for the magazine is a drawback. I stopped my subs because of space issues.
