[1] Webster was a contributing editor and columnist for the Science Fiction and Fantasy Writers of America Bulletin and published a collection of those columns titled Anthropology 101: Reflections, Inspections and Dissections of SF Anthologies through Merry Blacksmith Press.
After Helix SF ceased publication, he took his column, "Past Masters", to Jim Baen's Universe, and when that closed, to Eric Flint's Grantville Gazette.
The "Past Masters" columns are retrospective appraisals of so-called "classic" science fiction and fantasy authors, and include extensive bibliographies.
Some of the authors covered in the "Past Masters" series include Zenna Henderson, Fredric Brown, Edgar Pangborn, and Murray Leinster.
[2] In June 2013, Merry Blacksmith Press published a collection of Webster's essays about science fiction and fantasy authors and books titled Past Masters and Other Bookish Natterings, including articles on Clifford D. Simak.
This volume also includes short-short essays originally published in The Magazine of Fantasy and Science Fiction as part of their "Curiosities" column, as well as three articles co-written with Jerry Pournelle.
