There are many online catalogs that let you browse through, preview or add books to a virtual list. However they all treat each book individually even when they are part of a series. FictFact lets you track books by series and tells you which book is next in the series you are reading.
You can add a series to your account by searching for them and as soon as you get done reading a book, just mark it as read. You can also opt in to get email notifications when a new book belonging to any of your tracked series is coming out.
From a social perspective, you can share your series with friends, see what series they are reading and recommend authors, books and series to friends.
