Locus Magazine is a tremendous resource for anyone interested in science fiction. I've been reading it religiously for 25 years; nothing else comes close to its coverage of the genre. And in fact one of the nice things about SF as a field is it's compact enough that you can pretty effectively keep track on what's going on by just reading this one publication.
Which is why it's always a thrill to get the gala February issue of the magazine, where all their reviewers look back at the previous year's novels and short fiction and write up their recommendations and impressions. In addition, the reviewers and editors of the magazine do a collective mind meld to come up with the consensus best of the year for their "Recommended Reading List".
Here's the SF novels reading list:
The other lists, including fantasy, horror and short fiction, can be found here. And you might consider subscribing; the magazine provides a great service to the field and nobody's getting rich doing it.
