I’ve begun to assemble a comprehensive publishing industry statistics resource that everyone can use, which I’ll be keeping up to date. Why keep all that numerical goodness to oneself?
The first two sections, Book Sales and E-book Sales, are up now. You can always access the page from the Industry Stats Up-To-Date tab at the top of the page, as well.
If you have pointers to sites and statistical resources you’d like to suggest in comments, it will be greatly appreciated.
If you are a publisher of statistics who charge great piles of money for comprehensive reports, I would like to publish summaries that will help everyone and bring traffic to your site, where you will certainly sell more copies of your paid reports. You can reach me through the About page of BooksAhead.com
