There, I would catch-up on the latest issues of Cinefantastique, Starlog, and this magazine: Epi-Log.
You couldn't miss Epi-Log, because of its distinctive design. The covers always had a bright red logo, surrounded by bright yellow border. The latest issue would, I recall, literally seem to pop off the shelves, beckoning to me.
Today we have web sites, the IMDB, and other places where we can research episode titles, writers, and casts for TV programs, but in 1990 the best source for all that data was Epi-Log magazine.
Each issue of the magazine featured several episode guides, and often grouped series together in a kind of specific theme. For example, I seem to recall an issue that compiled most of the Gerry and Sylvia Anderson series. There was another issue I loved, that gazed at horror series such as Dark Shadows, and Ghost Story.
It's true that I rarely agreed with the publisher's commentary on specific series (he loved Lost in Space, but hated Space:1999), yet each issue provided a wealth of hard-to-find, incredible information.
