Wikipedia:Tip of the day/December 27, 2007
If you have privileged access to web pages...
The "perfect" Wikipedia article is built on solid research (remember to cite your sources). Contrary to popular belief, not all information is available for free on the Internet. Some research is only published in scientific journals and books (ask your library for remote lending services); some material is available only in commercial, password-protected electronic databases. If you have access to useful research material, please add the relevant information to Wikipedia:Research resources, a central portal to find Wikipedians with access to such resources. Remember we can only use facts from sources such as these, not a particular copyrighted expression thereof.
