- Book Revenue Data 2003
data on book
revenues in MS Excel format. The
list of books was compiled by
using the query "subject: fiction and pubdate: during 9-2003 and
binding: Hardcover" on amazon's
power search
to get a list of
all fiction on amazon published
during 9-2003. Of the 1913 titles listed, 1713 were in stock, had
prices
listed and were published in the correct month. The ISBN numbers for
these 1713 books are recorded on the spreadsheet and the prices are
those listed on Amazon. The total
sales are through 11-2004 and represent sales reported by Ingram
through their voice reporting system at 615-213-6803. The data for
September 2003 was collected during November 21 - December 4, 2004,
while the September 2004 data was collected during November 14-27,
2004.
2004. Sales data was available for 1284 of the titles. According to the
Yahoo profile
Ingram's 2003 revenue was $2.2 billion. According to Association
of American Publishers total book revenue for 2003 was $23.4
billion, which would mean Ingram represents roughly 10% of the market.
According to Google
"answers" Ingram's market share is roughly 1/6th, a somewhat higher
market share. The 2004
data was
generated the
same way as the 2003 data, but using publications in 9-2004. For 9-2004
there were 1388
titles listed 1235 were in stock and in the correct month, and 1153 had
sales data. Note that the results of the Amazon query is not identical
every time the query is run, and that the sales data except for the
year 2003 is also subject to change over time, so it is impossible to
exactly replicate this data. However the variation due to these changes
is small. In searching for ISBNs, bear in mind that they are 10 digit
numbers without commas; the
spreadsheet inserts commas and suppresses the leading zeroes. Data collected by Hengjie Ai, University
of Minnesota.
