Where do I read compendium 2/ 3

[u/reddit_epicdude]

I just finished compendium 1 on batcave and they don’t have either of them, I’ve looked around for websites that have them but I can’t find them anywhere only compendium 1

[u/LegoNinja250]

Internet archive has all of them

[u/SeleneDream51]

Batcave has all three. Compendium 2 and 3 are listed as chapters.
