A one-year old book on Loop Quantum Cosmology, translated into English, by Martin Bojowald, is out. Peter Woit reviews it
here.

The current entry for Quantum Cosmology at Wikipedia is absolutely woeful, and needs to be expanded. This is all it currently is:

In theoretical physics, quantum cosmology is a field attempting to study the effect of quantum mechanics on the formation of the universe, or its early evolution, especially just after the Big Bang. Despite many attempts, such as the Wheeler-deWitt equation, the field remains a rather speculative branch of quantum gravity.

An important problem in this field is the origin of physical information in the universe.
