\begin{abstract}
This bibliography attempts to give a comprehensive overview of all the
literature related to the Ashtekar connection and
the Rovelli-Smolin loop variables. The original version was
compiled by Peter H\"ubner in 1989, and it has been subsequently
updated by Gabriela Gonzalez, Bernd Br\"ugmann, Monica Pierri,
Troy Schilling, Alejandro Corichi and Christopher Beetle.
Information about
additional literature, new preprints, and especially corrections are
always welcome.

%When this bibliography was last updated, Bernd Br\"ugmann included
%some suggestions for the non-specialist. These are intended to serve
%as entry points into the literature. Here are his suggestions:
Here are some suggestions, intended to serve as entry points into the
literature.
First of all, for a complete and authorative presentation of canonical
gravity in the Ashtekar variables there is of course Ashtekar's latest
book [2] which appeared in 1991. The most recent general introduction
to the new variables by Ashtekar are his Les Houches lectures of 1992
[379].
The latest and up to date book in the `loop representation' is the
book by Gambini and Pullin [12], specially in lattice methods and
the `extended loop representation'. Many recent articles can be
found in the book by Ehlers and Friedrich [9].
Rather complete reviews of canonical gravity
in the Ashtekar variables
can be found in Rovelli [189], Kodama [233] and
Smolin [247]. For a critical appraisal of canonical
quantum gravity see Kucha{\v r} [277]. An overview over different
approaches to quantum gravity is given by Isham in [9].
More recent reviews on the two most prominent viewpoints, namely
the `connection' and `loop-spin networks ' representations are
given by Ashtekar et. al. [385]
on one side, and De Pietri and Rovelli [448] on the other.
A {\it dialogue concerning the two chief World systems}
is given in [487].
Finally let us mention a few more specialized references. A clear
and detailed exposition of connection dynamics is given by Romano in
[298]. For newer developments related to matter couplings (geometric
approach) see Peld\'an [369]. The definition of the loop representation is
discussed in Br\"ugmann [7]. Pullin [372] gives an introduction to
results obtained via the loop representation in (unreduced) quantum
gravity.
