Let's say you have the whole database of books from Amazon/GoodReads, including title/authors/genres/publishingdate/userrating/sales.

You'd like to make a recommendation engine, the idea is that the user could input 1-3 books they liked and it would suggest more books that are similar.

What sort of algorithms should I look into to do that sort of things?

Note that I don't have user profiles with what book they read, only have the database of books, can't do the recommendation engine based on two users liked the same book so they will also like other books either of them liked.
