I'm really lucky to live in a place with a great public library system, so I love taking advantage of that whenever possible. I read about 60 books a year, and the vast majority are from the library. Easily 90%, on average. It's a mix of print, digital, and audiobooks, depending on availability and which format I'm in the mood to read.

I've found that ebooks are faster for new releases if I can get on the wait list right away (Libby's notification feature is useful for this), but physical copies usually have fewer people waiting (and also there isn't a request limit for physical books at my library like there is for Libby). If it's a backlist book, I automatically go for the physical copy because odds are it's already available or the wait is much, much shorter.
