The sample screen above shows two user interfaces for accessing the e-print
archives. The window in the upper left corner shows abstracts received via
e-mail, and the window in the lower left corner shows the graphical user
interface provided by a WorldWideWeb client
(in this case OmniWeb.app running under NeXTstep) accessing the frontpage
(the underlined text signifies network hyperlinks
which bring up new hypertext when clicked upon). A paper extracted from
the e-print archive appears in the window on the right side, where it can
be read or sent to a printer.
This screen grab shows another WorldWideWeb client, Mosaic, accessing the
"form interface" on xxx.lanl.gov.
The Motif "buttons" allow the client
to choose an archive to view monthly listings, daily abstracts received,
or to search the title/author listings of selected archives for given time
periods. Listings are displayed in hypertext with included hyperlinks that
retrieve paper abstracts or full text in either TeX or Postscript format.
The number of http (hypertext transfer protocol) requests to the WorldWideWeb
interface on xxx.lanl.gov per day starting from Jan 1, 1994.
The seven day periodicity is evidence that many physicists
still do not have readily available network access on weekends.
