Help with a server report

Ok, I have to write a research paper on servers and music. For a project we have to do this year, I'm creating a music server, one where local bands in my area can put their music on it and (theoretically) then have the server installed somewhere where people can listen to their music. I was just wondering if anyone knows of any sites where I can find some good general information regarding servers, their use, how they've improved, etc... things like that. If anyone could please help me with this it would be greatly appreciated.
