Search limits help make most searches more specific.
Search limits may be applied prior to executing a search, or to a search results set (post search limits).
One or more of the following search limits can be used (please read the "restrictions and cautions" below) :
The button, used prior to executing a search, can be selected for any search method, but it has NO EFFECT on Subject, Author/Creator, or Call Number Browse searches.
The button is only available when viewing a Titles List or a Titles List (Keyword). Selecting this button takes you to the Limits screen, where you can apply multiple limits to the existing search results set.
Once search limits are set (either before or after a search), they remain in effect for subsequent searches, until the button is selected. The limits also affect searches that are launched by selecting hypertext links in single catalog record displays.
Note: Search limits in the Library of Congress can be very useful for refining large sets of search results, but should be used with caution. Not all catalog records contain the data that is used to set limits. When multiple values (e.g., several languages) are recorded in a catalog record, limits can only retrieve on one of them. If relevant material is not retrieved after setting limits, clear the limits and modify the search.

For instance, a sound recording may consist primarily of spoken material, but with some musical accompaniment. In such cases, the type of material is recorded as "Nonmusic Sound Recording"; a limit by "Music Sound Recording" would not find this item.
An exception is material that is serially produced. For instance, a computer file that is issued serially can generally be retrieved either using the Serial or the Computer File selection.
Use the browser's [Back] button to resume searching.
