This is a fantastic service for ELECTRONIC ARTICLES (and print books) that CUNY does not subscribe to. Get in the habit of using this -- its easy! Sign up here with your NET ID and select "New Request: Article" - You will then receive an email with a PDF of the article in about 1-5 days.
You can also use ILL for full print books, chapters, and some AV materials.
Ask me if you need help with this! Everything is free -- (this is espeically helpful when you hit a "brick wall" in your search and its looks like you have to pay for an article: you don't! Just use ILL!).
