Of course there are many answers to the question of how fast major publishers move their books after publication, but I am looking for something like the truism I once heard on the radio and cannot fully remember.
It was something like: Books capture 80% of their ultimate sales within the first six weeks after publication. Does anyone know of industry data on this?
Certainly e-books and print-on-demand don't have the same sales-vs-time curve, but I am looking for the experience of the major publishers and the books that are displayed most prominently on bookstore shelves.
Thank you!
