There are plenty of ways to organize book shelves. Some include by color, alphabetical, read vs unread, and many others. I’ve had many different book shelves and organization systems but the ones I’ve used the most are read and unread both keeping series together and keeping only the ones I’ve read together.
Currently, due to everything going on in the world I’m living with my parents so I’m able to have most of my book collection on shelves. During college I had one tall shelf and everything else was just stacked next to the shelf. Now days most of my books are on shelfs with some staked on the front of the shelfs. However, I do have some book mainly childhood favorites and college research text that I wanted to keep are in storage.
I’ve used different shelves and cases from different companies mostly from Ikea. Earlier this year some of the Ikea shelves started to fall apart and I purchased new bookcases from the furniture store, Havertys. I bought four in total, two taller with plenty of space to decorate and two that were smaller which fit better in the space but don’t have as much space on each shelf after books have been placed there.
My organization system works for me but I don’t think that it would work for many others. I first have separated all of my comics, manga, and lager coffee table type books from everything else. After that I organize by author and series so that all the books that I have by the same author and same series are together. If I don’t have enough books by one author for their own shelf I put other books or series that I feel fit best with them. Finally, all the books that I don’t have the next in the series or others from that author are organized by height starting with hardback and going to paperbacks. The only exception is that most of my mass-market books are on the same shelf.
This system works for me as I have a tendency to read all the books from authors I love and I get rid of books on a fairly regular bases. Because I go through everything at least once a year I would say that the organization changes a little bit every year and sometimes books are put where they fit.
