.: The latest issue (.pdf) of FreePint, #198, 19th January 2006, features a short piece by Roddy MacLeod, titled “Engineering: the changing information landscape”. Excerpt:
My first FreePint article on engineering portals appeared back in issue No. 66 (6th July 2000). Quite a number of things have changed since that time. The first part of this article revisits some of the resources I shared back then. The second section is an analysis of some useful engineering-related digital repositories which have emerged over the past five years. Finally, the third section comments on the changing engineering information landscape.
One observation that fascinated me is how the major engineering domains of the past have changed or disappeared altogether. This is definitely worth the read.
