What happened to Luke's archives?

As we know canon Luke had collected a mass amount of Jedi knowledge from Jocasta, the high Republic, the ancient texts etc.. So where did it all go?

And most importantly- where in the **** is his green lightsaber?

It's possible that Luke stored everything he had collected in his new Jedi Temple, and it was all destroyed here:

But hopefully that's not the case, and Rey(or whoever) will stumble upon it later -- it would be a shame if all that knowledge was destroyed. I mean, if Palpatine's relic room could survive the Death Star's destruction(and subsequent planetary reentry) there's still hope. /shrug

As for Luke's saber: there's nothing definitive on its whereabouts, but the TLJ novelization implies that he gave it to the caretakers of the ancient Temple on Ahch-To when he first arrived there.

This is new to me. I had just figured Luke stored his saber inside R2.

Alcida-Auka verified that one of the daughters had cleaned [Luke's] robes and put them away in the storage hut, along with his woolens, pack, and boots. She directed another daughter to take his weapon, his star compass, and his strange other gear to the repository, where it would join other items gathered over the generations.

That said, aside from his saber, I'm not sure what other "weapons" Luke would've had with him at that point? It's not like he was still carrying around a blaster when he went to Ahch-To. /shrug
