OMNI magazine blended science and science fiction, and was one of the most influential publications in the history of both. We draw on the influence of OMNI Magazine every single day, and so do a ton of other people, whether they realize or not.

So there's great news - pretty much the entire run of OMNI is available online at the Internet Archive. (And there's a complete index to the magazine here.) [via The Verge, thanks Walter!]
