This specimen of convolute binding really put into a quandary. This volume included a year's worth of Russian magazines Printing Art ("Печатное искусство".) And it had one of the pages from the first issue cut out.
Another find at a thrift store. I love everything about this Bible. The cover pattern is amazing. How the book feels in your hands. And I suppose the repairs were done by the previous owner after long and heavy use.
Bookbinding involves a lot of precision craftsmanship. Making a lasting object that can open and close out of paper, leather, cord, and an adhesive isn't a simple task. The nitty-gritty of book mechanics is a lifetime of study and practice.
