I'll update the indices we watch, in the case of book sales averaging around the first of each month to eliminate some of the random fluctuation.
Our Loop publication index uses the Spires base with DESY keywords "spin, foam", "field theory, group", "quantum gravity, loop space", and "quantum cosmology, loop space".

2005 40
2006 82
2007 121
2008 129
2009 125 (as of 30 November)

Here is the link for 2009 papers:

==========

Salesrank performance of Zurück vor den Urknall ("Before the Big Bang")
at 6PM Berlin time, compared with the average rank of the 3 currently most popular string books

29 November 0.78
30 November 0.67
1 December 0.74
2 December ?
3 December ?


To illustrate how the index works, at 6PM central European time on 30 November, Zurück ranked 9080, and the three most popular stringies (which happened to be Stoff, Verborgene, and Elegante) ranked 4526, 5859, 7800 for an average 6061.7 and a ratio of 0.67. In other words Bojowald's book was doing about two thirds as well as the stringy benchmark.

Trouble with Physcs, Amazon salesrank performance compared with five most popular string titles.

1 January 0.6 (2009)
1 February 0.7
1 March 0.5
1 April 0.6
1 May 0.6
1 June 0.7
1 July 1.9
1 August 0.6
1 September 0.6
1 October 0.4
1 November 0.5
...
30 November 0.56
1 December 0.54
2 December ?

To illustrate, at noon California time on 30 November, Trouble ranked 13570 and the five most popular stringies (hyperspace, elegant, fabric, parallel, black hole) ranked 4054, 4759, 4914, 5811, 18300, for an average of 7567.6 and a ratio of 0.56.

String publication rate for the first 10 months, measured using the Harvard abstracts database with keywords superstring, M-theory, brane, AdS/CFT, heterotic, compactification. As of 30 November the 10-month figures (successive years, through the end of October) for 2007, 2008, 2009 were 4143, 4071, 4038.
