SURVEY ARTICLES:
A survey of the whole field of approaches to QG
which is interesting partly for historical and broader perspective is
Carlo Rovelli's
Strings, loops and others: a critical survey of the present approaches to quantum gravity
http://arxiv.org/gr-qc/9803024
" I illustrate the main achievements and the main difficulties in: string theory, loop quantum gravity, discrete quantum gravity (Regge calculus, dynamical triangulations and simplicial models), Euclidean quantum gravity, perturbative quantum gravity, quantum field theory on curved spacetime, noncommutative geometry, null surfaces, topological quantum field theories and spin foam models..."
another broad survey

Quantum Gravity
( Lectures given at Karpacz. 40 pages)
==============
QG PHENOMENOLOGY:
Efforts and proposals to test QG are of increasing importance.
QG testability (Phenomenology) was the topic of the Winterschool-2004 (WS-2004) symposium this year, 4-14February, at Karpacz.

click on lectures if you want slides from the various talks.
Many of the talks are now written up as journal articles and available
on arxiv----more complete and faster download.
Cambridge Uni Press is publishing "Universe or Multiverse" which will contain a chapter by Smolin called "Scientific Alternatives to the Anthropic Principle" where he offers an evolutionary Multiverse hypothesis that generates testable (numerical) predictions.

EXTENSIONS OF SPECIAL RELATIVITY
Much QG phenomenology focuses on modifications of Lorentz symmentry---connecting quantum gravity with DSR namely "DDSR" or "TSR" ( triply special relativity)

Time dependence in Quantum Gravity
http://arxiv.org/abs/gr-qc/0408094
This recent paper has an extensive bibliography with many arxiv links, so
I will refer to that instead of posting them.
Here is the abstract:
"The intuitive classical space-time picture breaks down in quantum gravity, which makes a comparison and the development of semiclassical techniques quite complicated. By a variation of the group averaging method to solve constraints one can nevertheless introduce a classical coordinate time into the quantum theory, and use it to investigate the way a semiclassical continuous description emerges from discrete quantum evolution. Applying this technique to test effective classical equations of loop cosmology and their implications for inflation and bounces, we show that the effective semiclassical theory is in good agreement with the quantum description even at short scales."

Loop quantum gravity effects on inflation and the CMB
http://arxiv.org/astro-ph/0311015
from their abstract:
"In loop quantum cosmology, the universe avoids a big bang singularity and undergoes an early kinetic-dominated super-inflation phase, with a quantum-corrected Friedmann equation. As a result, an inflaton field is driven up its potential hill, thus setting the initial conditions for standard inflation. We show that this effect can raise the inflaton high enough to achieve sufficient e-foldings in the standard inflation era. We analyze the cosmological perturbations and show that loop quantum effects can leave a signature on the largest scales in the CMB, with some loss of power and running of the spectral index."

On singularity resolution in quantum gravity
http://arxiv.org/gr-qc/0312094
this is especially interesting because they duplicate LQC results (for example by Bojowald) using an older version of quantum gravity, ADM variables, quantized metric. Shows that the removal of the big bang singularity doesn't depend on using a particular formalism.
We make them for you?
