A brief history of software version control from the 1970s to the present day. The article presents a general overview of version control than briefly summarizes a number of different version control systems. Most of the focus is on open source systems and the author doesn’t mention broad CM tools, such as Clearcase. I don’t think he gives enough credit to SCCS as the pioneering system in this area. In general, this is a good starting point for further reading (and googling) on version control.
