History of Sandwiches

History of Sandwiches. whatscookingamerica.net
Informative guide to the history of the sandwich, invented apparently by Rabbi Hillel the Elder. But also an interesting case study in copyright. Ms Stradley prominently displays her claim to authorship of the document and forbids any use of it without referencing. However it seems pretty clear that she has cobbled this history together from other sources. So wherein lies her claim to authorship? If she has just reproduced the research of others, then does she really have any moral right to assert that this is her intellectual property. I think not!
