TITLE: Texts on the General History of Contemporary Combinatorics
QUESTION [11 upvotes]: I am looking for some core texts (books, book chapters, papers) about the general history of contemporary combinatorics, starting, say, from the interwar period up to today. 
Texts about the history of computer science & the theory of computation might be ok, but I guess I want to focus more on the general history of the 'pure' mathematics side.
Most of the main works I have found so far seem to talk about the earlier periods. I am familiar with some of Gian-Carlo Rota, Timothy Gowers and Terence Tao's expository pieces, and also the many biographies of Paul Erdos. I am also familiar with Norman Biggs and Edward Brian Davies's work.

REPLY [5 votes]: 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. 
Edited 5 May 2016: This book appears to have been published as Combinatorics Ancient and Modern.
