From an Internet Archive Blog Post:
When Mike Blinder acquired Editor & Publisher magazine in October 2019, he inherited boxes of back issues that he put in a climate-controlled storage unit near his home in Tampa, Florida. Leafing through the old — and sometimes brittle — pages of the journalism trade publications, he noticed a reference to microfilm access to the content.
Blinder, a media consultant for more than 40 years, says he turned detective trying to track down the missing E&P on microfilm. The odyssey would take him to past owners and bankruptcy documents before discovering that the canisters of microfilm had been purchased and given to the Internet Archive to digitize and make available to the public for free.
When Blinder called Brewster Kahle of the Internet Archive and found out we had the microfilm for his back issues, he was very excited to find the microfilm was not only safe, but that the Internet Archive would digitize all of the issues at no cost to him. Blinder enthusiastically gave permission for the full 100-year history to be read and downloaded by anyone, anywhere – along with E&P’s International Yearbook and Market Guide. Going beyond the Internet Archive’s traditional lending system ensures it can be indexed by search engines and made maximally useful to readers and researchers.
