My blog has travelled with the printing press progression during the Renaissance, Reformation and Modern World (to 1900) and included the topic - Paper. I find that one couldn't exist without the other. We have learnt about the printers (Gutenberg) and how the press recorded little change over many years. I think that a time line may be a good insert at this stage. Some interesting web pages are:

With so much information at hand, I will proceed with the blog. Hope that interest does not wane.
