For Winter Soldier’s backstory, you definitely want to read Captain America and Bucky #620-628, with an emphasis on issue #624. Cap and Bucky goes over Bucky’s history, and #624 gives a really good over view of Bucky’s time as the Winter Soldier. I also suggest getting the Captain America: Winter Soldier tpb, which collects issues #1-9, 11-14 of Captain America vol. 5. This is where Ed Brubaker initially introduces the Winter Soldier, and is arguably the best retcon of a death in comics history. In fact, just read all of Captain America vol. 5, since it’ll follow Bucky in some way or another (it’ll have Bucky in the main character slot after issue #25 for uh… obvious reasons :’[ ). And the best series for all of your Bucky needs would be the Winter Soldier comic, which unfortunately came to an end, but with Brubaker at the writing helm for a majority of the series, along with inks by Butch Guice and colors by Liz Breitweiser, it was one of the best, if not the best comic series of 2012/2013.

I love Bucky and Natasha’s flawless teamwork. Or rather, I love how Natasha is using Bucky as leverage.

Captain America and Bucky #624
Personally, I refer to this as the Captain Communist sequence, and it is one of my favorite scenes involving Bucky. Mostly because it’s nice to see that he’s still a cocky little shit when he’s “Russian.” But also because that nifty flip he does off the awning and the fact that Bucky had mad shield throwing skills even before he was Captain America.
