Update on research posting rates based on the same database search in each consecutive year. The 2012 figures (as of 18 December = 353/366) are annualized for comparison.

Quantum cosmology research since 2009:
http://inspirehep.net/search?ln=en&...2y=2012&sf=&so=a&rm=citation&rg=50&sc=0&of=hb (430 found, as of 18 December)
The Loop papers represent about half of the quantum cosmology papers found, and a larger percentage of those most highly cited: e.g. 27 out of the top 30 papers citewise.
This search is specialized to find research that appeared 2009 or later exploring ways of TESTING quantum cosmology (phenomenology, comparing QC models with observation.)

A bit slow, it worked just now after about a 10 second wait, and came up with 66 papers.
