For the last two months, 25.4% of our Summon traffic has come from the
IP addresses we've given as "on campus", according to the stats
Serials Solutions provides. Note that another 11.8% came from the
local ISP that provides wireless for our students, so most of that
would be "on campus" at other institutions.

The A&I results are interesting. EDS seems to promote results from
their own A&I databases more highly than I would expect, and they're
certainly noticeable when blanked out with "cannot be displayed to
When Summon started showing A&I results there was some interesting
discussion on the mailing list - they're not immediately accessible,
so they're arguably not "in the library's collection". And Summon (as
does Primo) has an option to "add results beyond your library's
collection". There was some argument on the other side, that A&I
results are important to be included, so it seems that there is
librarian pressure as well as commercial/licence pressure.
