Hi Deb,
I utilize several sources for my book finds -
Some online sources: Bookmarks.com, Amazon.com, B&N.com - you can search by award winners, genre, new releases, editor's picks and so on.

Many larger independent bookstores issue email newsletters - do a Google search by genre/store/location or whatever criteria is important to you. From there, you can browse sites and select ones that you like and sign up for their newsletters.

Hard copy publications (in addition to Bookmarks) are NY Times Book Review (Sunday edition), New Yorker Book Review, Entertainment Weekly magazine, genre magazines (for ex: Mystery Scene Magazine, Sci Fi/Fantasy etc.)

Also check with your local library - my local branch just started offering recommended books via email - all you do is select your preferences (thriller, children's, nonfiction etc) and they will send you noteworthy books for consideration every month.

Hope this helps ...
