There are so many ways to organise books on shelves, I have even seen them done by spine colour. Looked really good but it would have been impossible to find anything. Whichever way, they do bring life and soul into a home.
I used to keep my books in random order so as by serendipity I would find a treasure when I was looking for something quite different. In the library people often asked for the yellow book on the bottom shelf which was not how they were catalogued!!
I keep my books in "content" order: all mysteries together, all poetry etc. The only author I do alphbetically by title is Agatha Christie as I collect her..your shelves look lovely--so pristine hugs, Julierose
That has to be such a great feeling.
