Welcome to Asatru!
There's the Poetic Edda and the Prose Edda - for the former, you can find the Bellows translation online, and the Hollander translation is a good one. And all the sagas as well - there are translations online for free at places like Sacred Texts and the Gutenberg Project; those translations tend to be older and not everyone can read from a screen, but free is free, you know? Still, worth shelling out for the Hollander at some point imo, it's a lovely heavy thing. Don't limit yourself to one translation, as different people translate things in different ways and have different opinions in their footnotes, and it's interesting to read a variety and see what you think.
There's "True Hearth" by James Allen Chisholm, which is short but concentrates most on practical things which you may find useful. This might have been the other one I recommended you, but honestly I can't remember. The other one I may have recommended is "Exploring the Northern Tradition" by Galina Krasskova, which is the first book on Asatru I read although now I'm not as much a fan of it, and rather recommend Paxson over her. Still, you may find it interesting.
"Our Troth" vol. I and II, edited by Kveldulf Gundarsson are big, rich books. The first is on lore and the second on practice. Very good, once you're done with the 101 books these are the ones you need on your shelf.
Hilda Ellis Davidson might be the most popular pure academic among Heathens. "Gods and Myths of Northern Europe" is the standard but she wrote quite a few. If you can get your hands on a copy of Road to Hel, it's worth a read.
For a bit more advanced stuff further down the line, Gundarsson's "Elves, Wights and Trolls" is brilliant.
If you're interested in runes, Paxson has a book called "Taking Up the Runes" that is a little esoteric but that I recommend. With it, S. Pollington's "Rudiments of Runelore" makes a good and more practical balance.
