If I'm in NYC, I check out some of the independent stores and see what they're raving about. Otherwise, I like NY Times, Elle and Vanity Fair for reviews.
ETA: and NPR, of course! They have wonderful book coverage.

Goodreads! But also my brother, since we have similar tastes.

Something to look into when you are checking out Goodreads, is to look at the ratings. Check out the number of ratings, which will give you an idea if the overall rating is even accurate. Then click on rating details to get the percentages of how many 5 star ratings it got vs. 4 star vs 3 star. Sometimes a book will have a 4+ overall rating, but the rating details will tell you if more people thought it was a 4 star book or a 5 star book. If it got more 5 stars than 4 stars, that means the majority of people really like it, and I figure I will too. If it got more 4 stars than 5, then it's more iffy. And if it's mostly 3 stars - forget it! I also try to only read books that get over 4 star ratings in general.

@Bao: Go find a book you really liked. Then look at the reviews. Find a reviewer who agrees with you and who has something like "Review also at LINK" or "Full review at LINK." Then "Compare Books" (might be a desktop thing only) to see if your tastes are similar. For example, my brother and I are 76% similar for the books we've both rated. I follow a professional reviewer who's 81% similar to me. Then when they read books and give them high ratings and good reviews, I know I might be interested!

@Bao: What @Adira: said. I'll usually look up one of my favorite books and then click on the profile of the review that resonated most with me. Usually, we'll have pretty similar taste in other books too!

My BFF and I have a "book club". Really, we just pick a dozen books (6 each) and read them at the same time. Usually we pick categories (in a vague attempt to branch out).

Otherwise, I whine when I run out of books and someone has pity on me and brings me a bag of books. If I get desperate, there's this fantastic place called "books between friends" that runs entirely on donations of books. They sell the books for a great price and there's always great stuff there. All the proceeds go to charity.

If I'm really desperate, I go to chapters. And get ONE book. Then whine more.

@Bao: haha! I'm glad I'm not the only one!
