Once you have located an article in one of these databases, copy down the information contained in the Source field. This is the information needed to locate the article. Search the telnet version of the catalog to determine where the material you need is located. Online sources can be valuable tools if they are valid, unbiased, accurate, and emanate from trusted sources. Databases supplied by the same vendor will look and act similarly.
Different databases have different truncation symbols.
LISA uses an asterisk, Lib Lit uses a dollar sign, and the telnet version of the catalog uses a question mark. To limit results in LISA to research articles, include terms related to research in your keyword search. Ulrich's International Periodicals Directory is a good source to use to determine where a serial is indexed and if it is refereed.
