Library database vendor EBSCO now has exclusive deals with content providers — Time, Inc., and Forbes. Libraries who had been getting access to this same content through other vendors will have to pay up or lose electronic access to popular titles such as Sports Illustrated, Time and People. Gale, a competing vendor, has responded with their Fair Access campaign including the Librarians for Fair Access facebook group.
tl;dr version: If your library doesn't have EBSCO and wants to continue to offer electronic access to some magazines, they will have to get EBSCO. Previously, most magazines were aggregated and sold by many companies, more about the specifics here.
According to Gale: "If you currently receive Time Inc. or Forbes periodical content electronically from Gale or any provider other than EBSCO, you and your patrons will lose access to that content over ."
What changed? EBSCO responds, in Library Journal "In many cases, an exclusive relationship is the only way you can have the content in your databases." They were the top bidder in an RFP put out by Major Magazines who felt that they were losing revenue because too many people read their magazines in the library for free. That said, EBSCO is no stranger to the idea of exclusive contracts.
