The eSequels database, a new addition to the CRRL database offerings, is a great resource for book lovers. eSequels is "a reader's guide to novels in series," and allows you to browse by not only author and title, but also by character, location, and subject, allowing you to identify any series easily.
Series are also listed in the correct reading sequence, and annotations do not reveal any spoilers. The keyword search is a wonderful tool for discovering new series. The listings include only adult titles.
To access eSequels, click on the database title in the listing and then enter your 14-digit CRRL barcode on the main page.
