I'm almost tempted. I spent many, many hours boxing up the living room books over the weekend as Sam the Painter is coming in while we are in Spain. When they go back on their newly painted shelves perhaps I will have a bash at a rainbow filing system. (Only that would mean Zola's Rome in blue would be separated from the red bound copy of Zola's Paris. Would they pine? ).Elvis Costello ordered his record collection geographically - west coast to east coast - and my eldest says he has a similar system for his already extensive library.
Any other - non alphabetical - method for books, vinyl, CDs, DVDs....?
