Using Specific Publication Information
Results can be narrowed by defining the criteria of the publication information at the same time as you enter words or phrases in a keyword search. Most often, this information involves titles, authors and publication dates.
For instance, in a search regarding the impact of computers on writing instruction, you may want to limit the results to sources published after 1990. Generally speaking, most library catalogs, databases, and publication indexes will have an Advanced Search capability for this purpose.
In the screen-shot below you can see how the publication date of an "impact of computers on writing instruction" keyword search is defined using SAGE, the online catalog at Colorado State University's Morgan Library.
Note: This technique is less effective on Web site search engines because the dates when indexed sites were created or posted to the Internet are not necessarily part of the available record.
