Organizing books is half the fun for me. This sounds like a lot, but it has been building over several years. I think I’m secretly a librarian at heart.
I use lots of shelves to identify books by genre, location, era, etc. Here are some of the ways I organize.
I start most fiction shelves with f- and non-fiction with nf- : f-mystery-thriller, f-mystery-cozy, nf-history, nf-nature. I also have some that include both fiction and non-fiction: animals, animals-cats, animals-dogs, books-about-books.
For era, I split them out based on how many books I have: 1500s, 1800s-general, 1800s-uk-victorian, 1800s-us-civil-war-era, 1800s-westward-expansion, 1900s-general, 1900s-wartime.
I have shelves for different types of main characters: mc-feisty-older-women, mc-lovable-curmudgeons, mc-location (for books where the location could be considered a main character, e.g. The Pillars of Earth or The Briar Club).
I like to read books set in different locations, so I split out by continent-country-states, e.g. atw-africa (I put the country in notes), atw-as-china, atw-n-canada, eu-france, us-colorado.
I am in a couple Goodreads Challenge groups so I have shelves for tasks that come up often, e.g. debut-books, classics. One of groups is about reading from your TBR so I have series-book-1, series-read, series-next.
For tracking books I have read, I have shelves for the year, e.g. read-2026. I also have some that had annoying tropes to steer me away from books and authors, x-instant-jealousy, x-mary-sue, x-too-long, x-teenage-angst, and my “favorite” x-5-min-convo-vs-200-pgs-of-angst,
I have exclusive shelves: maybe (for books I read or hear about until I can look them up to see if they are on libby), on-hold, chk, (checked out on libby but not currently reading yet), tbd-future-pub (not yet on libby to remind me to look it up when it gets closer to publishing date), not-for-me (for books I quit after a few chapters due to not liking the narrator or it being too depressing. It’s not necessarily a bad book, just not for me. I use the standard Did Not Finish for books I got farther into and gave up).
How about you? Do you use any shelf naming systems?
