Re: Decision making by Libraries on serials and monographs and useage (re puzzled by self-archiv

I don't want to engage the argument between Sally Morris and
John 
Houghton, but I do want to point out an error of fact in one
of 
Houghton's sources. Houghton quotes Chris Anderson's The
Long 
Tail (not a very good book, by the way:  read it and see) to
this 
effect:  " 'if the Amazon statistics are any guide, the
market 
for books that are not even sold in the average bookstore is

larger than the market for those that are.'"  This is
simply 
wrong.

Amazon's statistics are not a guide.  It is apparently true
that 
Amazon's sales come predominantly from "long tail"
titles, but 
Amazon has enormous market share for those titles--for some

titles that share is 100%.  For better-selling titles (the 
130,000 Houghton cites, though a figure a third of that
would 
make more sense, if the aim is to reflect the realities of 
bricks-and-mortar bookselling) the share is distributed
across 
thousands of booksellers.  The market for books outside the
top 
130,000 is decidedly not bigger than that for the 130,000.

To the extent that Houghton's argument is propped up by 
Anderson's authority, it has to be said that Houghton's
thesis is 
unproven.
