Weak Gravitational Lensing
http://arxiv.org/abs/astro-ph/9912508
Article by Matthias Bartelmann and Peter Schneider about the statistical analysis of weak lensing effects that can be used to gain information about the large-scale mass distribution within our Universe.
Strong and Weak Lensing Constraints on Galaxy Mass Distribution
http://arxiv.org/abs/astro-ph/0112123
Review article by Jean-Paul Kneib about the way that gravitational lensing can be used to infer the mass distribution of galaxies (including the detection of dark matter).
Lectures on Gravitational Lensing
http://arxiv.org/abs/astro-ph/9606001
Lecture notes by Ramesh Narayan (Harvard-Smithsonian Center for Astrophysics) and Matthias Bartelmann (Max Planck Institute for Astronomy) about the basic concepts and applications of gravitational lensing.
HubbleSite News Center: Gravitational Lenses
http://hubblesite.org/newscenter/archive/releases/exotic/gravitational-lens/
List of images taken by the Hubble Space Telescope of Gravitational Lenses (including the famous Einstein Cross picture); updated continually.
Gravitational Lensing with Wineglasses
http://www.slac.stanford.edu/~pjm/lensing/wineglasses/
Explains how gravitational lensing can be simulated using wine glasses as (unusually-shaped) glass lenses. Includes images and diagrams to explain the different phenomena gravitational lensing can produce. By Phil Marshall (Stanford University).
Gravitational Lensing in Astronomy
http://relativity.livingreviews.org/Articles/lrr-1998-12/
Review article by Joachim Wambsganss, published in Living Reviews in Relativity. Provides a brief history of gravitational lensing, an overview of the basic physics and of the variety of lensing phenomena, and an outlook on future research.
Gravitational Lensing from a Spacetime Perspective
http://relativity.livingreviews.org/Articles/lrr-2004-9/index.html
Article by Volker Perlick (Technical University, Berlin) published in Living Reviews in Relativity about gravitational lensing in curved spacetime (as opposed to descriptions that rely on slight relativistic deviations from the Newtonian-Euclidean description of gravity and space).
Gravitational Lensing
http://www.iam.ubc.ca/old_pages/newbury/lenses/research.html
A popular site with interactive demonstrations of gravitational lensing. The background material is at a graduate level
Gravitational Lenses
http://vela.astro.ulg.ac.be/themes/extragal/gravlens/bibdat/engl/grav_lens.html
Site hosted by the Universit de Lige; features a bibliography, a list of lensing candidates, and descriptions of didactical experiments (involving glass lenses) useful for a better understanding of the phenomenon.
Gravitational Lens Data Base
http://www.cfa.harvard.edu/castles/
Homepage of CASTLEs, a gravitational lensing survey based at the Harvard-Smithsonian Center for Astrophysics. The main feature is a data base, complete with images, of all gravitational lens candidates that astronomers have identified so far.
