Newly organized notes, outlines, synopses, drafts, page proofs, etc. covering the development of the entire Fleet of Worlds series are now available to literary researchers (and the curious public). Many thanks to the Special Collections & Archives Department of the University Libraries at Northern Illinois University.
"This collection houses materials pertaining to the 5-book Fleet of Worlds fiction series co-authored by Larry Niven and Edward M. Lerner from 2007-2012. It consists of manuscripts in various stages of development including partial drafts, copyedited versions, and publisher page proofs as well as research and correspondence between the collaborative authors."
You can read all about the Niven/Lerner collection here.
Something to consider the next time you'll be near DeKalb, Illinois.
(I posted about the similar availability of my solo authorial archive last year, in "A Milestone.")
