It looks like our Loop publication index might be a bit down this year from last. But still roughly the same level as 2007 and 2008, keeping the gains made since 2005. The index uses the Spires base with DESY keywords "spin, foam", "field theory, group", "quantum gravity, loop space", and "quantum cosmology, loop space".
As of 17 November the numbers of publications in successive years were:

2005 40
2006 82
2007 121
2008 129
2009 115

Of course not all the 2009 papers are in, since we still have the remainder of the year to go. In case anyone would like to check out this year's papers, here is the link:

==========
Martin Bojowald's book is still doing pretty well. I check sporadically---take its amazon.de rank at 6PM Berlin time and compare with a string benchmark,the average rank of the 3 currently most popular string books.

Salesrank performance of Zurück vor den Urknall ("Before the Big Bang").

9 November 1.6
...
11 November 0.5
12 November 0.7
...
14 November 0.9
...
16 November 0.3
17 November 1.4


To illustrate, at 6PM central European time on 14 November, Zurück ranked 8253, and the three most popular stringies (which happened to be Stoff, Verborgene, and Elegante) ranked 6349, 6867, 8250 for an average 7155.3 and ratio 0.87.

Again, at 6PM central European time on 17 November, Bojowald's book ranked 8808 and the three most popular string books (Stoff, Elegante, Verborgene) ranked 8647, 13307, 14385 for an average of 12133, making the ratio 1.38.
=============

Yesterday I glanced at the noon standing of Smolin's book. It was at 40% of the string benchmark.
First of month figures this year have been:

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
...
...
16 November 0.4

The figure yesterday, 16 November, was not especially good, but not terrible either. The five most popular stringies at noon today were parallel, elegant, hyperspace, fabric, black hole. Average salesrank 6510.0. Trouble with Physics ranked 15,958.
