Information Impermanence

As you search for information, save your sources, particularly datasets and government publications. Note the date you were last able to access a source in case it isn’t available later. Check the Internet Archive’s Wayback Machine and other repositories for removed data sources or websites.

Citation managers can help you manage the information you save about your sources. You can reference and cite information that is no longer available where you found it. For these citations, include a last accessed date.
