Does this exist online?
I would for instance love to have a look on the stuff the people in the 16th century would read... And not only the famous stuff... :-)
What languages do you read? A lot of this would be in Latin, not English, at least for the 15th and 16th centuries. I do research in French and Latin and the Bibliotheque nationale de France has vast amounts of archived material available online — gallica.bnf.fr
The British Library has online collections as well — bl.uk/manuscripts
