I have a giant mixture of how I discover new books, but my biggest thing is mainly browsing local library website and their weekly lists of new releases as well as different book review aggregator sites
Osmosis.
I don’t actively seek out books to read - I just keep my eyes open and stumble across more than enough of them.
Same!
I enjoy talking about books, so I end up sharing favorites and news with a lot of people. Usually, I get more recommendations than I’m able to read.
Recommendations from friends and people I follow online, mainly. I follow a bunch of authors and narrative designers and between all of them I haven’t ran out of books for my wishlist yet!
In addition to “osmosis” that the other user mentioned, which is my main way of finding new stuff: I subscribe to a newsletter about new releases that comes each Tuesday. Also from friends with similar tastes in reading, and a lot of time from checking the works cited and recommended reading sections in nonfiction books.
It’s most from recommendations. From a friend, or online (previously reddit, now lemmy). Historically, my way to choose a book, is if I like something from a author, just start going through their full bibliography. So, a single recommendation of a new author can last me a long time.
These days, I am getting recommendations from our weekly “What are you reading” threads over at !books@lemmy.world. So many books are mentioned each week, my books wishlist has already grown quite a lot from it.
