According to our chart, that remark was in no way inflated. Yet, in spite of this spectacular outburst of publications in the 1640's, and after a short period of turmoil, the return of Charles II to the throne in 1660 brings things back to normal. If we were to take into account every single published item today, that figure of 2000 titles is probably much inferior to the published production of a single day in 1998 England. Together with the inflation in the number of published titles and pages comes a significant decrease in quality. Details matter less when you are reading about the latest news of the war.

The titlepage is the reflection of the book as a whole, its own self-reflection. The English book of that time chose to represent itself as free of any petty decoration.
