New Online Public Access Search Facility Those who have searched NARA’s online catalogue — Archive Research Catalogue (ARC) — will have known what a tedious exercise it could be, trying to find all of the documents whose title bears the searchword you have entered. All that has changed. It has been totally revised and is now very much like the online search procedure of the National Archives at Kew, and is now called the Online Public Access (OPA). To find what you are looking for, this is the procedure: Visit http://www.archives.gov On the opening page click on "Research Our Records" link. Then click on "Online Catalog" and enter your search word. On the left side there is a column that allows you to refine your search to "date range", "type of material" and "location". Click on the ones as required, usually only the date range if, say, you are only interested in a certain period in time, and click enter. On the bottom half of the page that appears click on "View all Descriptions Only". All documents bearing your searchword will now appear, sometimes with a brief description. Click HERE for an example of what you will get. Note that the searchword in this case is "Allison V-", to sift engines from other subjects with Allison in the title.

Ministry of Aviation (AVIA) One can obtain one's own list of document titles by visiting The National Archives
site catalog search page. Enter the Word or Phrase (e.g. engines, Rolls-Royce, Wright, America, Rockets, etc.), the Year Range (e.g. 1939 1945) and Department or Series Code (e.g. AIR, AVIA, DSIR, FO, etc.). A reminder: just because the word 'engines' is in the file title does not mean that the contents are about engines.
