Useful Physics Resources on the Web

The world wide web is a rich source of information about physics.  The Physics FAQ is not the place to put together a complete list of them so I will concentrate on databases that are packed with useful content such as physics news.  (Editor's note: many of the original links that this page referred to no longer exist, but I have updated the ones that are there.)

[Please don't ask us to add a link to your site from here.]

American Institute of Physics
The AIP publishes and archives a number of informative newsletters.  This is a good place to look for brief reports on recent discoveries.
High-Energy Physics Literature Database
This is a good site to search for the latest in literature on high-energy physics, as well as more general physics.
The American Physical Society
They publish some of the most important Physics Journals such as Physical Review.  On-line access to those is restricted but the News Room is a useful resource.
The Institute of Physics
Another journal publisher with a News section.
Los Alamos E-print Archive
For better or worse, these archives are one of the primary means of communicating new papers in the fastest moving physics disciplines.  Unfortunately, the lack of real competition for archives in this e-print area is perhaps what has given the archive's maintainers a very exclusive attitude that probably prevents much good research from being published at arxiv.
Particle Data Group
This is where you will find the Review of Particle Physics containing values for all manner of physical constants.  They have also put together an educational feature called The Particle Adventure.
John Baez's Papers
Useful information on developments in physics including the archive of This Week's Finds in Mathematical Physics.  John has also put together a tutorial on General Relativity.
National Institute of Standards and Technology
Another site with convenient tables of physical constants.
FreeHEP
A collection of free software for High Energy Physics.
The Laws List
An alphabetically ordered list of laws and principles of physics by Erik Max Francis.
Eric Weisstein's World of Physics
Another alphabetical list of physics definitions and equations by Eric Weisstein.
MacTutor History of Mathematics Archive
This is an extensive archive of historical information which has good coverage of physicists and astronomers as well as mathematicians.  Go straight to the search page and enter the name of your favourite physicist or topic.

If you still have not found what you are looking for, try the usual search engines such as Duck Duck Go, Start Page, or Google.  It is also a good idea to search old usenet posts using Google Groups.

Don't believe too quickly the top-voted entries on physics-discussion sites such as "Physics Stack Exchange", or the conversations on "Physics Forums".  The answers given on these sites are supplied by members who are often just trying to raise their "site star" rating, and so these answers tend to be what is naively believable rather that what is correct but possibly difficult.  Also, a form of voting on such sites gives rise to an abuse of power, such that long-time members can vote down good answers, or can even close down entire conversations.

Another site not to take too seriously is Wikipedia.  Wikipedia is probably fine if you want to know the population of Bolivia, but you should take it with more than a pinch of salt when looking to learn physics.  The reasons are several:
