Test your URL in a different browser (e.g., Firefox vs. Chrome) to verify that it is stable.

• A stable URL often ends in .htm, .html, a slash, or no file extension.

A URL that is long and complex, or specific to your session, will not work for every reader:

• A URL with the word "ezproxy" or "session ID" and your school's name will only work if you're logged in.

Don't evaluate your source by the URL.

• ANY company or organization can buy ANY top-level domain (.com, .org or .net)
