RBCC featured fan-generated art, original articles, and advertisements from comic book fans and dealers.

"[1] Inspired in part by the science-fiction fanzine/"adzine" The Fantasy Collector, in 1961, Jerry Bails, "the father of comics fandom," created The Comicollector as "a publication devoted primarily to the field" rather than the occasional advertisements of comics for sale that appeared in The Fantasy Collector.

Between 1968 and 1973, comics artist Don Newton produced almost two dozen covers for the Rocket's Blast Comicollector.

From 1972–1975 comics historian James Van Hise serialized his (and Larry Bigman's) "Al Williamson Collector" in the pages of RBCC.

Love published RBCC until 1974, when he moved from Miami to Houston, Texas, where he became involved with Star Trek fandom (and co-produced Houstoncon '74 and '75).

In 2002–2003, James Van Hise temporarily revived The Rocket's Blast and the Comicollector, publishing four issues out of a new headquarters in Yucca Valley, California.

Other columns, most of which appeared a few times at most, were contributed by Bernie Bubnis, Phil Seuling, Paul Gambaccini, Calvin Castine, Tom Fagan, and Rick Weingroff.
