Cut the binding off with a tablesaw and scan it with a scanner that has a sheetfeeder.
Assemble the scans into a pdf file using Adobe Acrobat.
I use "Steal This Book" by Abbie Hoffman as an example.
This book is somewhat hard to find in libraries, possibly because of its title. It consists of about 80,000 words on the subject of how to get by without consuming much and cause trouble for authority figures. At the time it was written the U.S. was conducting some upopular wars and many young people concluded that the whole "system" was evil. The tone and content of the book reflects this.
Abbie is no longer with us but I've asked a couple of his kids what they thought of my scanning this book this way. Both said they didn't think their dad would mind. If you are the publisher and you object, let me know and I'll scan one printed by someone else.

Step 1: Saw Off the Binding
If you want an extra clean cut use a new thin-kerf blade and clamp the book between two boards. Then you could use a push stick and it won't look like your hands are going into the saw as in this view.
