For those not in the know, Locus Magazine is, as its subtitle suggests, The Magazine of the Science Fiction and Fantasy Field. It is the pre-eminent magazine covering the genre publishing industry, prose fiction, and conventions, featuring reviews, news, interviews, publishing data, and more.
With the January 2011 issue, which will focus on SF in the digital age, the magazine will publish its first digital edition. The digital editions will be available in pdf format at first. Epub and Kindle editions might come in the future. This is good news to be sure.
