Search the PSU Library catalog for books. When you find a pertinent book with a green Available at PSU Library shelves link, select it or the title link for the full record. Write down the location and call number. To locate the call number on a floor map, select the link, View Map. Check out the book at the 1st floor Circulation Desk.
Use Google Scholar from the PSU Library, and enter the title of the article. If the Library has the article, there will be a link to the right, Find it @ PSU.
Find it @ PSU leads to the full text article in the PSU Library catalog.
If it is not available full text through Google Scholar, PSU Library could still hold the article in print. Search for the journal to see the Library's holdings. If the library does not hold the journal at all, request it from Interlibrary Loan & Article Delivery.
