Renaming to Aliens (comic book), Aliens (vol. 2), and Aliens (vol. 3)
I felt positive that "volume" was meant instead of "series" (which tends to suggest the whole enchilada of comics branded "Aliens"). Looking at the indicia (the small print on the inside front page) for the second miniseries (the Dennis Beauvais one) it does indeed say "Aliens vol. 2". Issues of the first 1989 miniseries are just called "Aliens" until "Aliens, Volume 1" appears in the January 1990 graphic novel.
