Golden Age Comic

The Earth-2 Robin, Robin from the golden age? If yes, what comic / STPB I need to read to follow?

I am a newbie to the whole thing multiverse So please anything right, I said it's wrong. Nevertheless, I'm a fan of the Golden Age Robin but apparently his adventures "never counted after the crisis or whatever (never read). Either way, someone Could he tell me some pocket books or comic series, I'd be playing so I can follow the 40 adventures of Robin in adulthood?

I believe that the Earth-2 Robin was eliminated during the crisis. On Earth-1, the original Robin became Nightwing and is now the guardian of a town near Gotham appointed Bludhaven. Bruce Wayne then took another orphan and made his headquarters. It was Jason Todd. The Joker has killed quite a few years ago. The next to follow that Robin is Tim Drake and he is currently the last I read. Robin wears a long pants, and finally now instead of this strange looking underwear.
