Useful message (especially for the britarch editors) about one of
the problems that come with e-publishing. Apols if people have
already seen it elsewhere.

A very interesting article in today's _Science_ on the problem of non-
permanent web addresses in scientific and medical articles.
"Internet references in medical and scientific periodicals may become
more common as 7 million pages of new information, including data not
available elsewhere, appear daily on the World Wide Web. .....
However, unlike hard copy references, Internet references may change
and become inaccessible"
http://www.sciencemag.org/cgi/content/full/302/5646/787
Looking in just three journals (NEJM, JAMA and Science) they found
that after 27 months 13% of internet references were inactive. About
half of these were recoverable via Internet Archive or Google.
