At George Andrews' web site there is a link to an article "Partitions". He refers to this as chapter eight in History of Combinatorics, edited by Robin Wilson. Robin Wilson has a list of Book Projects in which he describes this book as follows:
"History of Combinatorics, Mathematical Association of America; an edited collection of articles on topics in the history of combinatorics: target handover date, end-2008."
But I can't find anybody who's saying that they've written some other chapter of this book. Nor can I find any reference to it at the MAA web site. Perhaps someone else reading this knows more about the status of this project.
Edited 31 May 2011: I came across this old answer of mine and decided to dig around a little more. John Watkins, recently retired from Colorado College, is apparently working on this project with Wilson. This June 2010 Mathematics Magazine article about Euler squares includes the following citation for another chapter:
L. D. Andersen, History of latin squares, Department of Mathematical Sciences, Aalborg University, Research Report Series R-2007-32, 2007. To appear in The History of Combinatorics, R. Wilson and J. Watkins, eds.
