Software Library?

Our company has grown to the point where we need to have a central repository of software. I have been tasked with collecting all original copies of software around the office. We don’t ever want to let the original copies get out to the users, soI had the idea to buy a server with a lot of disk space to copy all the original CDs to. That way, my users can simply install software over the network.

Do I have the right idea here, or is there a better way to do this?
