DWPI on Delphion is no longer available, as of March 31, 2012. DWPI data is available on the Thomson Innovation platform.


Delphion provides an update schedule at, which is changed as the individual collections are loaded (which should be almost every business day, since each collection is released on a different day of the week). The schedule is an html schedule, which means that previous weeks’ records are erased as new records are added.

Links to ISI Web of Science records are updated monthly, although both Delphion and the Web of Science collections are updated (at least) weekly.
