Records Control Schedules
These requests for disposition authority documents are agency requests to NARA submitted since 1973. Older items may have subsequently been superseded by more recent submissions. Please see the FAQ for more information. Questions about active disposition authorities should be directed to the agency records officer.
NOTE: NARA’s process for determining which records schedules in the RCS are currently valid is an ongoing work in progress. Records schedules will be marked inactive when all items on the schedule have been superseded. Before implementing disposition using these records schedules, always verify that you are using the most recent and current disposition authority (or item).
Tip 1: Use Phrases in Quotes
Example: "audit files"
Without quotation marks, any page containing the words "audit" OR "files" will appear in results.
When surrounded by quotation marks, the words are treated as a phrase and only pages with the exact phrase "audit files" will appear in results. This is the most powerful query refinement technique.
Tip 2: Use a Plus (+) or Minus (-) Sign to Require or Reject Words
Example: audit files +system -withdrawn
You can require that the word "system" be in any documents in the results list by placing a plus (+) sign before it.
You can reject words with the minus (-) sign.
In the example, no documents with the word "withdrawn" will appear on the results page unless a search engine is programmed to make them appear above the regular results list.
Tip 3: Combine Tips 1, 2
Example: audit files +"Internal Revenue Service" +system
By combining phrases with a plus (+) or minus (-) sign, and capitalizing where it's appropriate, you can increase the relevance of search results.
Tip 4: Spell Out All Acronyms
Example: Internal Revenue Service (IRS)
Avoid using acronyms for instance: IRS for Internal Revenue Service can be mistaken for another acronym such as IRS-CI and effect search results.
Tip 5: Searching by Job Number
NOTE: You MUST enter the job number in the correct format. Consult the SF 15 Numbering Key if necessary.
