Data on galaxies -good references ?

[notknowing]

I'm looking into galaxy rotation curves and I was wondering where I can find a good (preferentially recent) overview of measured galaxy rotation curves (refereed journal article, good website, arxiv ..). Further I was wondering how far out (from the galaxy center) one can measure rotation velocities and whether one has observed rotation curves where, at some large radius, the velocity starts to drop.
I'm grateful for your help.
