Only those books come down which deserve to last . All the gilt edges, vellum and morocco, all the presentation copies to all the libraries will not preserve a book in circulation beyond its intrinsic date.

Summary

This quote suggests that the value and longevity of a book are determined by its content and worthiness, rather than its fancy aesthetics or attempts at preservation. No amount of decorative touches or efforts to distribute copies will ensure a book's endurance if its content is not compelling or relevant. In the end, it is the intrinsic qualities and timeless ideas presented within a book that determine its lasting impact and circulation.
