Case Sensitivity
Queries conducted in this system are case insensitive. A word entered in lower case will match words entered in upper case, lower case, or mixed case.

Pick Lists
To assist you in formulating queries using the Search screen, PICK LISTS have been created for select fields. PICK LISTS are menus of standardized values that are valid for a particular field. You can select one or more pick list values from the drop down menu. To select one, simply click on the value(s) you want included in your query.

Sorting Search Results
This database allows you to sort your search results. To use the sort feature, simply click on the drop down arrow to highlight the field you wish to sort by. Then select either ascending or descending and initiate your search.

Wild Cards
The asterisk (*) is used as a wild card character for none or more characters. Using a wild card character allows you to search for words with the same prefix or stem. For example:

Declassification Status

There are four types of status assigned to the records in this database:

  1. Declassified: Indicates that the original document, which was classified, is now declassified and available for ordering. You will receive complete copy of the document.
  2. Sanitized: Some documents that are themselves still classified, have had the classified information removed so that a "sanitized" version of the document is unclassified and publicly available.
  3. Never classified: Some documents were never classified but were kept with classified collections because their subject matter related to the same event or topic. News reports and letters are document types which may never have been classified but were included in this database as part of an overall classified collection.
  4. Unknown: The correct information was not provided for this document. It may have been declassified, sanitized, or never classified.
