According to Starr, "Publishing was associated with capitalism in part because the industry itself was a prime instance of capitalist development. The earliest printed books, like the manuscripts that served as their models, were large, cumbersome folios written in Latin primarily for the clergy, the universities, and higher officials." In this quote, it is implied that manuscripts were written in Latin and it were predominantly for high officials. Why was that so? Personally, I think that this was fair. Society doesn't just consist of high officials. Everyone should have had the right to read a manuscript despite their class.
