I have been turned on to more and more long book series by members here.  I have had trouble with a couple of them in trying to find the number of the book in the series as many times the place I first see the book is a book review. I thought the easiest way should be to click on the author's name so I see all their books in publishing date order, but many of the titles do not include the number, only put the name of the series in parentheses--- for example:  (Alan Gregory series) for the  series by Stephen White.  So, is there an EASY way to find the number?  (I volunteer in our FOL bookstore and have seen plenty of book series I don't read on the shelves and have noticed the number isn't anywhere on the cover for many series books either.)

Guess I should be glad I liked the Stephanie Plum  (numbers) and Kinsey Milhone (alphabet) series!!

I usually look for a list inside the book or try to google "name of book series list or order".

According to google, librarything.com has a list for Alan Gregory series.  I don't know if that site is always a good resource.

I use the Kent District Library "What's Next" feature.  Just plug in the author's name and it will give you the books in order of any given series.

goodreads.com, fictfact.com & fictionwise.com are great places to get series info.  On goodreads & fictfact you can track books, mark them as read, owned etc..,
 

Another good place to look is fantasticfiction.co.uk    If you look under the author's name, it will list all the books in a series in order, including new ones that are not yet out.

I always go straight to FantasticFiction.co.uk.     Or - if it's a mystery then another great source is StopYoureKillingMe.com.

Oops I just realized that I put fictionwise instead of fantasticfiction.com.  Fictionwise was a site to buy ebooks that closed. Sorry about that.  Fantasticfiction has more than just series but you can't track books there as far as I know. Great place to see all of an author's books and series order though.

I use FictFact.com. I'm lionrose there too, there's  a link in my profile. Great way to track series and keep track of what you need to complete a series, either to acquire missing books or what order to read. And if you find a series they don't list, they are really nice about adding it right away.

I love fictfact for keeping track of books in a series.
