Tips To Make Internet Searches More Effective
How can I cite an Internet source so that others can find it later?
Internet resources are quite dynamic, so sites may change addresses or disappear entirely. Be sure to take note of the title, author, date, complete URL (web address) and the date you viewed the material. That way, even if you can't find the web page again, you'll still have the information you need to include a complete citation in your reference list.
Once you have your information, check out the How to Cite Something You Found on a Website in APA Style blog post on the APA Style Blog.
