High Wire Press is "a division of the Stanford University Libraries; [it] hosts the largest repository of high impact, peer-reviewed content, with
1185 journals and 4,976,465 full text articles from over 140 scholarly publishers. HighWire-hosted publishers have collectively made
2,005,740 articles free. With our partner publishers we produce 71 of the 200 most-frequently-cited journals." The passage from the site seems to say it all.
