What is the third Wimpy Kid book? What comes after The Long Winter? Which book follows The Nutmeg of Consolation?
From time to time we have had print reference books to help you sort out the order of books in series, but the newest stuff is never in there.
So, try this great finding aid from the Kent District Library in Western Michigan.
Just be sure to spell authors' names correctly, and remember that guesses at series titles can be wildly inaccurate. If you get zero results, think it out, rephrase, and repeat.
