The web is an important source of information but a lot of its content should be treated with caution. A good place to start your search is from the Library's own list of Internet Gateways. These Gateways provide access to a wide range of web pages that have been evaluated and identified as appropriate for use by students in higher education.
The page also contains links for three of the major Internet Search Engines, if you wish to conduct your own searches using these resources, please view the Library's guide on how to search and evaluate the information on the web.
The list below includes some recommended websites for Physics:
Infomine - Physical Sciences, Engineering, Computing & Mathematics
Searchable database of internet resources in the Physical Sciences from the University of California, Riverside
The public interface of the Institute of Physics
The Physics Departments and Documents Network
