Google Scholar is a great tool if used as one of many resources, not as a primary resource. Because it is such a huge database of materials, many of them out of print or in restricted collections, it can be the place to find unique and useful research material.
If you are unable to find the full-text of an article in UDC databases or on Google Scholar, you may be able to request the article from another library in the Washington Research Library Consortium through Consortium Loan Service. Most articles will be sent to your UDC email address as a PDF file.
If you are unable to find the full text of an article in UDC databases, on Google Scholar, or at other Washington Research Library Consortium libraries through Consortium Loan Service, you may request the article from non-WRLC library through Interlibrary Loan (ILL).
