If I'm searching for articles on the internet, how can I tell if TC3 has a copy?

Answer

Install a browser extension called LibKey Nomad.

Go to thirdiron.com/downloadnomad/ and click Get LibKey Nomad Now.
Click the download button for the browser you are using and install the extension.
When you are prompted to Select Organization, start typing Tompkins... and then TC3 should come up.

Click on it and your choice will be confirmed.

If you are ever on a journal web site that asks you to pay for an article, check with your librarians. We can probably get a copy for you without you having to pay for it. See the Do I have to pay for articles? FAQ for more information.
