Ooh no; my books are sorted according to type generally, depending on the size of the shelves.
Largest bookcase has poetry followed by history and art; second largest a mixture of fiction, favourites and the classics, some children's books and general larger illustrated books. The narrow bookcase has plays, dictionaries and grammar books; maps and travel books, and six bibles (?); the alcove shelves have study texts and textbooks plus 'how to paint...' guides and the shelves in my bedroom have a collection of comfort reads and books to be finished , mainly novels. The spare room has more classics, novels, local history and reference, and the cookery books are in the kitchen. Would love a library room, (and more shelves).
My particular dislike is colour co-ordinated books, as seen recently seen in charity shops to celebrate Gay Pride.
