A genuinely spooky cover, courtesy Klaus Janson. I'm not sure what "Sagas" means, since one of these stories is only nine pages long, but:
"The Second Coming of Superman" by Cary Bates, Curt Swan, and Vince Colletta (a sixty-three--well, that's a saga--page story from Superman Spectacular #5)
"The One Minute of Doom!" by Edmond Hamilton and John Forte
"Let My People Grow!" by Len Wein, Swan, and Frank Chiaramonte
...plus a Superman vs. Brainiac pin-up by Jose Luis Garcia Lopez, that on the table of contents is listed as "from the 1982 DC Comics Style Guide." Editor Nick Cuti was being charmingly honest with that credit. Did most readers know what a "style guide" even was?
