To this end, I wrote a little perl script that takes a Spires querry on the command line and then downloads all pdf's that come up for this querry (actually the first page of the web results) to the current directory. To use it,
chmod a+x getspires, move it to some directory in your path and the for example
getspires a witten
to get Ed's latest or
getspires FIND C QJMAA,54,281
for a bibliography on generalized geometry.
