What is grangers plan for preserving books?

Please provide more context! Who is Granger, and what plan are you referring to?

For example, are you thinking of:

* Hermione Granger from the Harry Potter series? She is a fictional character and does not have a real-life plan for preserving books.

* A real-life individual named Granger with a book preservation plan?

* A specific book preservation plan that is named after Granger?

Please clarify your question, and I can provide a more helpful answer.
