I've recently (as of June 2010) finished writing a biography of Crockett Johnson and Ruth Krauss. That said, it's not too late to revise the manuscript. So, if you knew Crockett Johnson or Ruth Krauss, ever received a letter from either of them, know something that I don't, or have ideas to offer, please contact me. My email address is philnel@ksu.edu. You may also write me at this address: Department of English, ECS Bldg., Kansas State University, Manhattan, KS 66506-6501. The book's likely publication date is 2012.
