If you are like me and you read lots of books that are part of a series, I have two resources for you. I use both of these in the library. I absolutely HATE to read books in a series out of order so I refer to these all the time.
1. The first site is Fantastic Fiction http://www.fantasticfiction.co.uk/. This is from the UK but they cover all of the major and even lesser known US authors. You type in the author's name and you will get lists of their books by series in chronological order. They also have the author's upcoming books. I especially like the list they include of authors who write similar style books.
2. The second site is Stop You're Killing Me http://stopyourekillingme.com/ . This is a mystery site. They also list authors books in chronological order with the upcoming one at the end. Each page is easy to print and bring to the library or bookstore to keep track of what you have read by a particular author. On the home page, they have a month by month list of upcoming books. I subscribe to their email newsletter and it always has useful information such as award nominated mysteries or new authors.
Hope you find these sites helpful!
