Aside from the "official" magazines Starlog magazine served as the source publication that spawned a slew of other spin-off serial publications, including:

 

The Best of Starlog, Starlog Poster Magazine, Starlog Spectacular, Starlog Yearbook, Starlog Scrapbook, CineMagic (which specialized in focusing on VFX production staffers and techniques, intended to be a "light" version of American Cinematographer), Science Fiction Video Magazine, SFX Magazine, Starlog Photo Guidebook, and Starlog photo guidebook Special Effects, each of which with a varying degree of success.

 

The Starlog Photo Guidebooks were exactly what they sound like - thin, 8 1/2 x 11" paperbacks filled with stills from science fiction movies and TV shows, with descriptive captions and articles.
