@TheEdVerse Aside from the 3 core books, which 2nd ed books are worth getting in your opinion?

It depends. If you’re running a Realms-based campaign, I consider the Forgotten Realms Adventures tome, the FR Atlas, and the Volo’s Guides absolutely essential. Then I’d add Cloak and Dagger, and any regional coverage I wanted for my campaign (e.g. Waterdeep).2)
Then, if you're running a campaign that focuses at all on ancient ruins, I'd go and get the 3e Lost Empires Of Faerun book. If you're delving into the Underdark, the 2e Drizzt Do'Urden's Guide To the Underdark. If you're using yuan-ti, etc., the 3e Serpent Kingdoms, and so on.— Ed Greenwood (@TheEdVerse) April 22, 2020

Also, Power of Faerun (3e) and Ed Greenwood Presents Elminster’s Forgotten Realms (4e, but really edition-less) are useful in any Realms-based campaign.#Realmslore 4)
Some folk use religion and the gods heavily in their campaigns, and others less so. If you do use the gods, Powers and Pantheons and Demihuman Deities (both 2e) or Faiths and Pantheons (3e) are essential.
If you use tomes of magic, get Pages From The Mages (2e), ..#Realmslore— Ed Greenwood (@TheEdVerse) April 22, 2020

…and/or Prayers From The Faithful (2e) for holy books of magic. And so on. ;}#Realmslore— Ed Greenwood (@TheEdVerse) April 22, 2020
