On the history of evaluation in IR

I'm currently writing my PhD thesis and this paper is one of the gems I found: "On the history of evaluation in IR", S. Robertson, Journal of Information Science 34(4), 2008. You can find it here: http://jis.sagepub.com/cgi/content/long/34/4/439 (there's also a citeseer version for those without access I believe).

I think it's a must-read for any PhD student doing IR since it covers the fundamentals (and history!) of evaluation in IR. It's also written in a light and sometimes even funny style.

Enjoy :)
