>>85888868You could start from the beginning and marathon through but if you need a little help with some starting points/suggestions (there have been a couple of LoSH torrents around but I don't have a link)
Silver age: Adventure Comics #346
Bronze age: LoSH v2 #283
Five Years Later (you'll want to read it with context of the earlier stuff though): LoSH v4 #1
90s Reboot (first proper reboot): LoSH v4 #0, Legionnaires #0, LoSH v4 #62, Legionnaires #19, LoSH v4 #63, etc (they stop crisscrossing directly after like an arc or two but they'll crossover again at times as well)
DnA run: LoSH v4 #122, Legionnaires #79, LoSH v4 #123, Legionnaires #80 then Legion Lost (you could start with Legion Lost on its own but the context helps)
Threeboot (second proper reboot): v5 #1
Retroboot (sort of an unboot): mainly just the Johns arcs (JLA/JSA Lightning Saga, Superman and the LoSH, Final Crisis Lo3W)
Other cool things: Star Trek crossover, Morrison's Action run, Superboy's Legion Elseworld
Not exactly LoSH but you should read it: L.E.G.I.O.N. and R.E.B.E.L.S.
5YL gets shitty when Giffen leaves. Threeboot gets shitty when Waid and Bedard leave. Retroboot get shitty when Johns leaves.
There's a ton of minis that aren't listed that are ok, Mon-El had an ongoing and was pretty involved in New Krypton, etc. But I assume once you get a taste for things you'll probably read them anyway. I probably forgot something obvious.
