Many articles in Gale are available right away:

However, if you find a citation to an article in Gale that is not available in full text (no PDF button), we can request the article for you from another library.
On the page that lists the article information, click on the Email icon in the Tools menu (right side of the screen, as shown below).

A box will appear. In the "Mail to" field, enter library@centralpenn.edu. In the "Sender email" field, enter your email address. In the Message field, enter "Full text article request." Click the Send button.
(You can use an address other than your school address, but then please provide your full name so we can verify you are from Central Penn.)

The process is not immediate, but articles are usually provided within 2-3 business days.
You will receive an email either with instructions for how to access the article (a URL to visit and a password) or with a PDF of the article attached.
