I've put the series of posts I did a couple of years ago on the Sudeten crisis into one big PDF file called, rather grandiosely, Post-blogging the Sudeten Crisis: The British Press, August-October 1938 (147 pages, 5.6 Mb). It's freely available for download under a Creative Commons Attribution-NonCommercial-NoDerivs 3.0 Unported License. It's very bloggy in style, but I've also added a basic index and put in internal links between the chapters (posts). My Sudeten posts are probably the best thing I've done with this blog, and they've been linked to from a few educational sites as well as Wikipedia. So by putting them into this format I hope they'll be made accessible to a wider audience. (I've been inspired in this by the work Evangeline Holland has been doing over at Edwardian Promenade.)
The conversion was done using a nifty tool called WPTEX. This is some PHP which hooks into WordPress's functions and reads out and formats your posts into LaTeX format. It didn't quite do what I wanted but with some PHP and LaTeX hackery I think it turned out pretty nice in the end.
