The average traditional large scale
publisher chain bookseller have has (singular noun) a 60 day shelf life for titles—if less than 10 books per store, per location, do not sell they either place them in the clearance bins—or return them to the publisher.
Each day, corporations such as Barnes and Noble- Chapters (Indigo) return 95% of the original purchase order. (Note: I'd add "up to" before 95%, since it's not a fact, but an average.)
Out of 1.2 million titles submitted to distributors, only 15% are accepted
to by major bookstores. oOut of those 15%--13% are repeated high profile (Celebrities, business gurus, sports leaders)- or a niche market- (Note: a percent of a percent is a non-existent number for the purpose of a statement of fact, because it winds up a fraction. If 15% of 100 is 15, then 13% of 15 is 1.95. You might try to re-word this to an actual percentage of the original number, or leave out the percentage.)
Acquisition budgets for major libraries, retail outlets and schools have been cut 47% in the past five years. (Note: Is this a nationwide average and from what source? Because it's the other way around down where I live.)
Most media have reduced book reviews to either once a month- or they have cut it out altogether- (Note: There's a REALLY good article about this in the LA Times from last fall. It would be worth reading through it to include fair use quotes which will give more oomph to the statement.)
Marketing materials supplied to authors by the publisher who sell less than 5,000 books ( This means paid for not ordered for they may be returned)- zero (Note: I don't understand this statement. What are you including in the term "marketing materials?" Do you mean book specific marketing materials? Most publishers are happy to offer authors materials that are for the publisher itself or the line because that's not attributed to an individual book's overall cost.)
Book signings/ tours and readings for authors who sell less than 5,000 books arranged by the publisher-zero (Note: If this is geared toward readers who are authors with less than 5,000 sales, then this is fine. But it's actually a much higher number of sales required for publicity to take the time/money to arrange any of these.)
Media appearances arranged from the publisher for an author- zero- authors are expected to hire their own publicist. (Note: What is a "media appearance" that's not a signing, tour or reading? Do you mean like television, radio or newspaper interviews or articles? If so, then this section should probably be moved up to the part about the decline in reviews, because when the reviews declined, so did the OFFERS to interview authors.)
Each year over 1.2 million books are published world wide? And over 300,000 in the English language alone? Fewer than 20,000 will make it into the average book superstore. Most on the shelf of that superstore will not sell. Less than 2% of all books published pass the retail bar. (Note: The last statement doesn't fit with the previous two since the quality doesn't have anything to do with the shelving. Move it up to be the second or third statement.)
In 2004, 950,000 books out of 1.2 million tracked by Nielsen Bookscan sold fewer than ninety-nine copies. Only 25,000 sold more than 5,000 copies. The average book in North America sells about 500 copies. (Note: Why is this separated from the previous statements. I'd resplit these paragraphs---one about lack of sales in stores, and one about the difficulty in getting published in the first place.)
According to the Book Industry Study Group 2004 Books Sales for NA were 1.2 million. (Note: I think it's important here to mention whether this is ALL books published (including small press, self-pubbed and ebooks) or just the large commercial publishers. It will make a difference in the reader's mind.) This means that your book is I out of 1.2 million titles for a buyer to choose from. Below is a chart of Sales Range and the amount of titles that sold in that range.
