Copying things is a contemporary as well as an antiquarian issue.
The German aristocrat, Karl-Theodor zu Guttenberg (a.k.a. Baron Cut-and-Paste), until recently the German Defence Minister, has resigned amidst revelations that he copied half of his PhD thesis (2006) (BBC report; for the data see here and also here).
Another aristocrat, Saif Al-Islam Alqadhafi (son of Col. Gaddafi of Libya), may also have some trouble with his LSE PhD (Independent; for the PhD see here). His topic? Ironically enough it was "The Role of Civil Society in the Democratisation of Global Governance Institutions: From ‘Soft Power’ to Collective Decision-Making?" Not too much collective decision-making in Libya at the moment it seems. (LSE is also in trouble for accepting £1.5 million after his PhD was passed.)
