Over the bed/cab roof racks?

Can anyone tell me what the over-the-bed and over-cab roof racks are called? I see these all over the place, but I can't find any info in the forums, or by searching the internet, so I'm guessing that I don't know what to search for.

These are the racks that I usually see bolted into the bed rails and create a frame that goes over the bed and cab.

Thanks for any help with this!

Thanks! "Ladder rack" is what I was looking for.
