The first printed books started to appear in the fifteenth and sixteenth centuries. And yet, all the way up to the end of the eighteenth century, we find many variations of the classics. This comes from two main sources: authors relied on others to do printing. Often, the printers would make mistakes and in-house style and shortcuts were often applied even at the highest quality printers. This is further complicated by original undated manuscripts: was the manuscript a draft? was it modified after the final edition? Furthermore, authors often revised their work and would print a new additional versions later in life: just consider Pope's _Essay on Man_. Many of the documents undated and determining the author's final intentions is non-trivial. Consider William Blake: he was incredibly meticulous in both his writing and engraving and many variations of his work abound. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
