  This bibliography attempts to give a comprehensive overview of all the
literature related to what is known as the Ashtekar-Sen connection and the
Rovelli-Smolin loop variables, from which the program currently known as Loop
Quantum Gravity emerged. The original version was compiled by Peter Huebner in
1989, and it has been subsequently updated by Gabriela Gonzalez, Bernd
Bruegmann, Monica Pierri, Troy Schilling, Christopher Beetle, Alejandro Corichi
and Alberto Hauser. The criteria for inclusion in this list are the following:
A paper in the classical theory is included if it deals with connection
variables for gravity. If the paper is in the quantum domain, it is included
when it is related directly with gravity using connection/loop variables, with
mathematical aspects of connections, or when it introduces techniques that
might be useful for the construction of the (loop) quantum theory of gravity.
Information about additional literature, new preprints, and especially
corrections are always welcome.
