The Grantville Gazettes are anthologies of short stories set in the 1632 universe introduced in Eric Flint's novel 1632.
The Gazettes started as an experiment: a professionally edited, officially sanctioned "fan magazine" published electronically. Initially released as serialized e-magazines, they were later published as e-books (taking a page from the Baen Books experience with E-ARCs—Electronic Advance Reader Copies, which had been instituted several years earlier.) Because the electronic sales were successful, Baen contracted with Flint for more issues, to be published 3-4 times per year (bimonthly, starting in 2007). Each would form part of the canonical background for the other works (novels and anthologies) in the rapidly growing 1632 series.
As of mid-2012, e-magazines are published bimonthly, and six books have been published (five of those as both hardcover and mass market paperback) excerpted from the first 17 issues of the magazine. A seventh book is promised.
