The University of Manchester (England, in case there is a university by that name somewhere else) Library has published a booklet of 25 pages called
First Impressions: How Printing Began. It is a
free pdf.
Here's a short description:
The PDF . . . is an introduction to printed books. It looks at how books are printed, where printing started and the early pioneers of the printed word. Great for a background to printing, looking at inventors or the spread of language.
The book looks to be very well done. It is certainly attractive. From what I gather, the book is intended for children, though not young ones--probably preteen to early teens. So why am I not posting it on a children's nonfiction thread? Well, sometimes I don't want a large book with "heavy" text that forces me to have to concentrate a whole lot. Sometimes I want a book like this one to get a quick overview of some subject. In fact, I downloaded and saved it for myself for just that reason. Maybe you will find this tome to be just what you want, for that reason or some other one.
Ironically, this book about printing of physical books appears to be available only as an electronic book. ha
I'm going to give you two links here. One is
the direct link to the pdf book and the other one is
the indirect link. The webpage that you get when you follow the indirect link also shows how you can access, also freely, some other nice resources on the same subject, including an interactive website on the history of printing.
