Thanks for your question. First, let me request that if any of the
following is unclear or if you require any further research please
dont hesitate to ask me for a clarification.
Based on Ingram data, obtained through Ingrams ISBN hotline, here is
up-to-the-minute data on the book with ISBN 0764122002
Copies on hand in Ingram distribution centers 80
Copies on order 32
Copies on back order 0
Sales for the week ending 3/30 23
Sales in 2003 through 3/30 345
2002 Sales 262
In order to assess the total number of books sold, industry analysts
apply a multiplier of between 6 and 10 to the Ingram numbers.
2002 sales between 1550 and 2620
2003 sales to date between 2100 and 3450 for ¼ of the year,
therefore anticipated sales could be pegged at between 8400 and
approximately 14,000 in 2003.
