The seventh chapter of Cohen and Rosenzweig’s book Digital History was pretty fascinating because it brought up the seeming difficulty in keeping your work posted online from being pilfered and pirated.  They bring up the point that unlike other areas (such as movies and music) historians are more concerned about their work being plagerized and passed off as someone elses rather than really wanting any royalties for it.  But then they ask the question: where do you draw the line between “fair use” and plagerism?  Fair use implies that historians cannot research and write in a vacuum; its only reasonable that they be allowed to use the works of others to guide their own.  And I agree with that…so long as they cite the sources they use and give credit where credit is due.  History should not be a selfish subject, there should be equal sharing of information all around so that historians everywhere can build off one anothers research to create a greater understanding of the past.
