I share your thoughts on bookshelves in general. I have lots of books on art and artists, coffee-table books on cities, etc., etc. The need for fitting bookcases has actually turned me into an avid amateur carpenter. I decided to make my own bookcases quite a while back and have continued the craft by making desks, work-spaces and other furnitures... I now really enjoy working in my "shed" designing the various components and making them. It has a similar "zen-ish" feeling to me as back in the days I use to develop and print my own films.
