I have over 100 books tagged as want to read on goodreads.
I pick books a variety of ways - I do read most of the books for book club. I put books on hold with Libby to read - and read some of those when they come up. I also tag books as want to read on libby - and have over a hundred tagged there - and some are available without a wait. I am sort of a late adopter so once I hear a lot of people saying they like a book - if it seems like something I'd be interested in - I tag it as want to read on goodreads or Libby.
Of course I do sometimes get "duds." I think other people can love a book and for whatever reason I don't - there's no way to tell for sure until you read it!
I usually read a sample of a book for a few pages before deciding that I'm really in the mood to read it. Sometimes when I can't pick what book I want to read next - I read a bunch of a samples until I find one that "grabs" me.
I don't like to read books the same author too close together. I'm a dork and I have a list of books that I want to read by the same author a year later. For example - last year I read and liked The Four Winds - so after one year had passed since I read that one - I allowed myself to read The Nightingale.
I don't love love love the Next Year in Havana / Chanel Cleeton books but I give them 3.5 stars and I think they're cute/easy. So anyway - same thing, I had read Next Year in Havana in probably 2019. Then read When we left cuba last year, and now that it's been over a year - I am reading The Last Train to Key West.
OK and finally - where I am also a dork is that I try to read every third book that I read by an author who is different from me - usually race or sexual orientation-wise.
Now you know my life story
