Hi! New to the fandom, and was hoping I could get some fic recs that feature Bobby's backstory.  We know what got him started in hunting, but how does he go from hunting noob to the bamf librarian, fluent-in-Japanese, whenever Sam and Dean are stuck they give him a call character he is in the series? 

There have been earlier searches for how Bobby and the Winchesters met, but I'd like stories that really focus on Bobby's evolution as a hunter and how he meets the network.

Any length, pairing(s), or ratings and self-recs are welcome too!
