Occasionally I will find documents which ought to be on the web but aren’t. The following is a running list of papers, hosted for academic purposes as fair use, that are perhaps interesting to others.

• Tobler W.R. ”Of Maps and Matrices“, Journal of Regional Science, 7 (supplement), 1967, pp. 275–280. Wiley, the publisher, maintains electronic copies of the journal but their volume 7 contains no supplement. They’ve been informed of the error (see case number 11069719) but after two years seem uninterested in fixing it. I have not hosted all the articles online, just this one which I discovered while researching the history of pattern recognition. If you want to see a very early (perhaps the first) demonstration of automated contour mapping, look no further.
• An unpublished paper by William Kahan and K-C Ng written in 1986, titled simply SQRT. The paper was distributed to a network of colleauges, and, strangely enough, a version of it is preserved in a widely distributed numerical library, fdlibm. In the only discoursive comment block in the whole library, nearly all of the paper is in machine readable text at e_sqrt.c. This scan was graciously provided by David Hough.
