This will help check that my information is up to date. You can watch the video at the bottom of this page for more information about using search engines.
Remember it is important to consider where your information comes from. Sites that end in .edu or .gov may be more reliable than those ending in .com or .org. Sites that end in .au may be more relevant to Australia than those just ending in .com.
