Start with The ABCs of Reloading for an overview:
The ABC's of Reloading, 10th Edition https://www.amazon.com/dp/1951115279/ref=cm_sw_r_apan_i_0ZP3WZ54GZP9PC3DAZPX
Then grab the Lee Reloading Manual and a Lee Anniversary kit to get started. That's what I did and it worked out for me.

If you are starting out these is one I would get and read it will guide you very well. https://www.amazon.com/ABCs-Reloading-10th-Philip-Massaro/dp/1951115279
That being said Hodgdon has all it's reloading data on their website for free. https://www.hodgdonreloading.com/
VihtaVuori Powder as well.

I like having multiple books to reference while I am loading.
If you are new to reloading in general, I strongly recommend reading, “The ABC's of Reloading” to give yourself a basic understanding of the process.
