An obsession it's true.
I've never considered books to have a shelf life, a sell by date, a best before date. But Seinfeld questions the use of books in just 8 seconds. Commercial shelf life is possibly the only sell by date that can be placed upon books.
An interesting notion to place upon literature though.
Jerry also manages to take away the objectivity of the book by simply saying,
"you read them? What do you need them for?"
Placing complete emphasis on a book as a capsule for content, knowledge, a story that, once taken in, has fulfilled it's purpose.
* Outcomes
A series of books that have a physical shelf life. Pages that decay, text that degenerates.
Books that question the objectivity of a book, a book as a trophy.
Books with an afterlife, once reading it, what is gained? How does the use of the book change? How does the readers relationship to the book change?
