Hello again Qpet,
Thank you for your question.
Where can I find sales numbers for books?
(For example 'One taste' by Ken Wilber sold X-copies)
You can call Ingrams "Freddie" line at 615-213-6803.
Enter the ISBN and select option #3;
You will hear a computer-voice telling you stock status in how many
Ingram warehouses; how many were sold this year and last year.
To obtain the ISBN number of One Taste by Ken Wilber I went to
One Taste: Daily Reflections on Integral Spirituality
by Ken Wilber
ISBN: 1570625476 http://www.amazon.com/exec/obidos/ASIN/1570625476/qid=1054941240/sr=2-1/ref=sr_2_1/102-6101053-1564936
I called 615-213-6803, entered ISBN 1570625476 and they gave me the
Total sales this year: 144
Total sales last year: 379
In order to calculate the total number of books sold, industry
analysts apply a multiplier of between 6 and 10 to the Ingram numbers.
Total sales this year would be in the range of 864 to 1440 copies
Total sales last year would be in the range of 2274 - 3790 copies
Another option is Nielsen BookScan. This appears to be a fee based
