Social media (goodreads/tiktok/reddit)? Colleagues? Friends? Browsing the library/bookstore? Asking for recommendations from staff at libraries/bookstores?
BONUS: if you can remember, how did you find books you really enjoyed?
I realized a lot of my favorite book recs came from reddit. I was a subscriber of r/books and picked up some really good books there. Piranesi by Susanna Clarke is an example.
Recommendations from people I know. Depending on who recommends them, I’ll pick them up. I also search for lists on google or “favorite book” polls/list on reddit. As long as I like the premise I’ll try it. If the first book in a series is a good read, I’ll continue the series, if not then I won’t. And of course books from authors I already knew when I liked their books.
