So I've almost finished collecting all the trades for the pre-New52 Nightwing series, and I have some other stuff featuring Dick like:

1.batman prodigal

2.Batman Black Mirror

3.The Outsiders (full run)

4. Nightwing (full New52 run)

5. Grayson vol1 (I will get the others when they come out)

6. Titans (2007 series)

7. Things like blood borne and the target.

I was wondering if their were any books that you guys could recommend with Dick Grayson in it. I'm always looking to further my collection!

For Pre-New 52 you can get Grant Morrison's Batman and Robin run, as that was featuring Dick as Batman working alongside Damian. There are about 4 collected volumes for it altogether.

Time and the Batman, Gates of Gotham, Life After Death, and Long Shadows are also tales that feature Dick as Batman. And all are solid. Really the only other thing i'd suggest would be the New Teen Titans run.

Maybe Robin Year One and Batman the Gauntlet if you want more about his time as Robin.

You should check out some of the older Teen Titans volumes.

I would agree with nathaniel_christopher about the New Teen Titans run and would even begin with the first issues from the 80s (before Crisis on Infinite Earths).

Teen Titans: Year One shows quite good how Batmans and Robins relationship works and logically how the first Teen Titans formed.

The Devin Grayson Titans run, back when Devin was a decent writer. No Man's Land was an epic Batfamily story in which Nightwing shows up a lot.

Morrison's Batman and Robin.

The first 2 volumes of Nightwing are available now By Chuck Dixon.

Robin Year One.
