There are a number of free online encyclopedias on the web to help you find what you need. Many are offered as complete reference sites with a variety of tools available.
Decide on your topic. A free online encyclopedia uses a search engine to find keywords, but as with any search you have to refine your search words to find topics that match your interest. Searching "skunk" can get you everything from how to get out the smell to how to keep one as a pet, so focus your search terms on the specific topic you need.
Step2
Look for how they package the information. Most free online encyclopedias divide their data into tools to make your research easier. Many offer timelines, text of speeches and historic documents in addition to articles. Some also target specific age groups with information tailored to that level.
Step3
Evaluate the source. Just because a website calls itself a free online encyclopedia doesn't mean its information is reliable. If you're researching a school project, check with your teacher or professor to be sure your source is acceptable.
Step4
Use a variety of sources. Although you may find relevant information in one free online encyclopedia, double check the facts. Conduct the same or similar search in another encyclopedia to confirm facts and compare results.
Step5
Go to the library for more tools. Some libraries subscribe to online encyclopedias and offer them free to patrons. Encyclopedia Britannica is one example that may be available through the reference desk of your public library.
Tips & Warnings
Many schools will not accept Wikipedia as a source. Because it accepts submissions from any user, information found on the site is not guaranteed to be reliable. Although its backers say they review all postings, the risk of using incorrect information is too high for many instructors.
