The library catalog, alas, doesn’t always list the actual volume number. Author websites are often so cluttered and junked up with graphics, it takes several clicks to get where you want to go.
You can register if you want to be notified when books are released. You can also add book ratings and then browse through lists of the most popular series (Young Adult, Science Fiction, Paranormal are some of the many categories). If you find something you like, recommendations for similar series are given. (One of my favorites is “Coffeehouse Mysteries.”)
You’ll find yourself losing track of time as you go from link to link and find more authors you want to check out.
