Analog is a tremendous publication, a long-running flagship of science fiction that never fails to impress and inspire me. It combines excellent fiction -- often with hints of libertarian thought sprinkled in -- with well-written, understandable science stories. This is hard SF at its very best. The Web site reprints some of the magazine's monthly columns, and features the full-versions of those stories nominated for speculative fiction's top honors. Like its sister magazine Asimov's, Analog's Web page isn't tremendous, but it works.
