Golarion Elf & Dwarf source material

[heliodorus04]

I'm a big fan of Golarion; it's one of the things that attracted me to Pathfinder. I have the Inner Sea World Guide, so I know some basics about Kyonin and the Dwarven Kingdoms from that book.

I'm wondering what other source material might help me better understand the history of the core rulebook non-human races, especially Elves & Dwarves.

I hope to (in the pipedream sense) design a campaign that jumps to an earlier point in Golarion history (post death of Aroden still, but anywhere thereafter is fair game), and I want to tell a Dwarf/Elf focused narrative, aiming for 1/3 or less players as human.

What else might I read to better know Golarion's (particularly Avistan's) Dwarf/Elf societies.

Second Darkness has some background material, such as the origin of Drow.

The only major things that have been covered for either are the Quest of Sky for Dwarves, and the Retreat of the Elves before Earthfall, the corruption of the ones that stayed, and the Elves' return.

There's Elves of Golarion and Dwarves of Golarion, although the elf book in particular predates the Pathfinder RPG and has some relics of 3.5dom in it, such as elves not sleeping, iirc.

A lot of the early/mid part of Queen of Thorns takes place with outsiders to elven culture dealing with elves.
