Kansas City, MO. (06/03/2005) Bill Watterson has placed more than 3,000 original Calvin & Hobbes comic strips from his personal collection on long term deposit at The Ohio State University Cartoon Research Library.

According to the library’s curator, Lucy Shelton Caswell, “Bill Watterson is unusual among cartoonists since he kept virtually all of his original comic strips. The collection he has placed here is unusually complete. We are delighted to have this archive.”
