What is a book:
Here is a simple introduction.
1. Here is a good link to a video series on bookbinding. The stitching structure is simpler and less durable. But otherwise the same. Here they make a hard cover.
2. On Books and how the technology of books and book usage shapes subjectivity etc:
In the Vineyard of the Text, Ivan Illich. This is an exceptional book looking at the impact of the book as a system on thinking.
A B C: Alphabetization of the Popular Mind, Barry Sanders & Ivan Illich. This is an early work looking more broadly at the question of how writing has impacted thinking.
3. Early Greek Subjectivity:
The Greeks, Jean-Pierre Vernant. This book is a good overview of ideas of classical greek subjectivity.
