Looking for new books to add to your summer reading list? You probably already know to check sources like Goodreads and the New York Times book reviews, but that’s not always enough. Here are a few of my favorite non-obvious sources for online book recommendations.

Shelf Awareness for Readers

This free, twice-weekly email newsletter from book trade publication Shelf Awareness launched in 2011 and is still one of my favorite places to learn about new books. The newsletter comes out on Tuesdays and Fridays (or you can read it online) and in each issue, independent booksellers and reviewers recommend 25 books that have just hit stores. While some bestsellers from big authors are included, plenty of books from small presses and debut authors are also included, making this a good place to learn about books you probably wouldn’t have heard of otherwise.
