Let's shine a light on where to find these 1940s tales a little closer to modern times!
Though having more stories focused on Hal Jordan, Green Lantern #30 is reprinted in Green Lantern: A Celebration of 75 Years of 2015, which also features Hal's first appearance, the first appearances of Sinestro, Guy Gardner, John Stewart, Itty, Kyle Rayner (as Green Lantern) and the first solo meeting of Hal and Alan, which gives the origins of the Guardians (and the first appearance of Krona and "the cosmic hand", which could be the earliest recorded look at the DC Universe as well as a hint of how the scientific Green Lanterns of Earth-1 related to the magical Green Lantern of Earth-2!).
This story was first reprinted in Detective Comics #440 (April-May, 1974) under a Jim Aparo cover, with a new Batman story and new Manhunter story, as well as a Silver Age Hawkman and Golden Age Doll Man and Golden Age Manhunter reprint. This story was also reprinted in the Green Lantern Annual #1 that looks like it came from 1963, but was really made in 1998 (and focuses more on Hal Jordan, and meetings with Star Sapphire, Sinestro and the Flash!).
Ironic then that it should be reprinted in Green Lantern #89 (April-May, 1972), under a cover by Neal Adams, featuring the last of the Green Lantern (Hal Jordan) and Green Arrow team-ups in their own title by Denny O'Neil and Neal Adams.
But, not unlike Hal and Ollie, Alan Scott has more stories to tell (and a few more solo Green Lantern tales reprinted....though way too few!).
This story was reprinted in the Green Lantern: A Celebration of 75 Years in 2015.
Wildcat, Mr. Terrific, Johnny Thunder, Atom, and more!
This story was reprinted in The Great Comic Book Heroes of 1965, Secret Origins of the Super DC Heroes of 1976, and leading off Green Lantern: A Celebration of 75 Years in 2015. Amazing how Alan was allergic to appearing on covers of his reprints!
This tale was reprinted in Wanted, The World's Most Dangerous Villains #4 (December, 1972) under a cover by Nick Cardy (and with a reprint of Kid Eternity facing his foe, Master Man, as well). It was in the 1970s that Solomon Grundy became more well known to the world as a member of the Legion of Doom on the Super Friends cartoon!
This tale was reprinted in World's Finest Comics #211 (May, 1972) under a cover by Neal Adams (and an odd Superman/Batman story at a time when Superman was teaming up with everyone BUT Batman). Sadly, this is Harlequin's only solo GL reprint (her appearance in All-Star Comics was collected), but at least you can read about where to find her original tales here!
This story has been collected twice, once in Green Lantern #86 (October-November, 1971) under a cover by Neal Adams, and later in the Greatest Golden Age Stories Ever Told of 1990 under a Jerry Ordway cover (along with tales from Black Canary, Dr. Mid-Nite, Johnny Quick, and more). Wouldn't it be great to see the Icicle's first tale reprinted as well?
This story is found in Detective Comics #443 (October-November, 1974) under a cover by Jim Aparo, with Batman and the Manhunter in battle with the Council, and reprints including the first appearance of the Creeper and a Golden Age Spectre reprint. Sportsmaster also joined the ISW, and sadly, has Golden Age appearances not reprinted as well.
Thankfully, a few more Golden Age Green Lantern appearances have been collected as well.

Unpublished Golden Age Green Lantern tales
Odder still was Green Lantern's part in an unpublished Golden Age Flash story, featuring the Thorn, of which two pages were reprinted in an issue of Lois Lane (this had a huge impact on Alan's future, as well as the life of Jade and Obsidian of Infinity, Inc.).
At least all of the Golden Age Green Lantern's appearances with the Justice Society of America were collected when all 57 Golden Age issues of All-Star Comics were collected in the multiple volumes of the All-Star Comics Archives! Would that we get more reprints of Golden Age Green Lantern stories to shed their light on the evil of not being reprinted....
