The Center for History and New Media at George Mason University has consistently broken new ground with their projects, and this online resource is an important part of their work. Created and written by Professors Daniel J. Cohen and Roy Rosenzweig, this online version of their book serves as an introduction to the web for those "who wish to produce online historical work, or to build upon and improve the projects they have already started in this important new medium." The work is divided into a number of chapters, including "Becoming Digital", "Owning the Past?", and "Preserving Digital History". Leaving hardly a stone unturned, the work covers everything from copyright law to site design, and it is a work that visitors will want to return to more than once.
