Instructions
for Searching ALL Correspondence and Organizations
 

 

NOTES:

1) Only summary results are produced by searching across all correspondence and organizations. For more detail, perform further searches among the specific "Originating Organizations".

2) Conventions for the dates take several different forms, which are detailed below.
    a) yy -- a single year with the leading "19" omitted.
        (50 = 1950)
    b) yy yy yy yy -- a string of years separated by spaces.
        (36 38 39 41 = 1936, 1938, 1939, 1941)
    c) yymm -- year and month
        (4803 = March of 1948)
    d) yymm-yymm -- a range starting and ending with year and month
        (4803-4902 = March of 1948 thru February of 1949)
    e) yymmdd -- year, month and day
        (480618 = June 18, 1948)
    f) weyymmdd -- week ending year, month and day
        (we480618 = week ending June 18, 1948)
    g) yymmdd-yymmdd -- a range of dates
        (390726-390915 = July 26, 1939 thru September 15, 1939)

3) The results produced by searching the organizations may include abbreviations for the designers and manufacturers of aircraft, engines and propellers. Click here for a current list of abbreviations.

 


Instructions for Searching ALL Correspondence and Organizations

This search process involves a Search Form and a Results Form.

Below is a portion of an example Search Form:

 

Unlike the individual Correspondence and Organization searches, you must specify a search criteria for the ALL Correspondence and Organizations form. Here we have entered "p-66". Clicking the "Search" button produces a Results Form, an example portion of which appears below:

 

The Results Form

In order to specify useful search criteria, one must understand what appears on the Results Form, so we will cover it first and then return to the Search Form.

Please remember that the object of this finding aid is to tell one where the records are located at the National Archives II (hereafter Archives). One must still travel to the Archives in order to view the records. The finding aid makes a visit to the Archives much more productive. All fields contain information that can be searched and are further explained below.

RD #
Every record that is in this collection is part of Record Group 342. The Record Group, in conjunction with the four-digit RD # displayed in the Results Form, is required to actually get the physical document box containing the desired record when one visits the Archives. Members of the Archives staff can help to correctly fill out the paper forms required to retrieve records for viewing. Note that multiple records may exist in the same box.

Date
This field specifies the date or date range during which a project was active.

Title
A searchable Title field is the whole point of this Finding Aid. For the first time, one can rapidly locate the records that are applicable to a specific subject. The titles were assigned by the AEHS volunteers who produced the box lists for Power Plant Lab projects. They are as descriptive as practical and include key words that will make searching easier.

Remarks
This expands on the Title to provide additional information, such as the type and quantity of data.

Doc #
The Doc # is analogous to the RD # described above, except that the Doc # pertains only to the Microfilmed Memorandum Reports. The Doc # is structured as follows: Orrffff where,
O = the Engineering Division Organization that originated the Memorandum Reports (P is the Power Plant Laboratory)
rr = the Microfilm Roll Number within the organization's Microfilmed Memorandum Reports
ffff = the Frame Number on the Roll.
Hence, P020641 means that the Power Plant Laboratory Memorandum Report begins on Power Plant Laboratory Microfilm Roll 2, frame number 641.

File #
All Engineering Division records were once organized according to an arcane scheme called the War Department Decimal Filing System (DFS). Most of the Correspondence Records are still organized according to this DFS. The table at the bottom of the Search Form lists some of the more common DFS Classifications.

Subject: This is the title on the file folder containing the correspondence record of interest, and presumably the subject of the report or other documents contained therein.

 

Search Again
Clicking on Search Again returns to a CLEARED Search Form. If you desire to return to the search form and preserve the search criteria, use the browser's "BACK" button.

 

The Search Form

 

The search will return results matching ALL of the search criteria that are specified, limited by the Max Records pull-down menu located under DISPLAY OPTIONS.

The text of either the Title or Remarks fields can be searched by selecting either the Title or Remarks radio button and entering words or phrases into the next series of menus, which produce results as outlined below:
all
of the words: results containing ALL of the words in this field (separated by spaces, in any order) are returned.
the exact phrase: results containing the exact phrase specified in this field are returned.
at least one of the words: results containing one of the list of specified words.
none of the word(s): results that contain any of the words in this field (separated by spaces), in any order, are returned.
The _ wild card character may be used within the Title or Remarks specification to match any single character.

DISPLAY OPTIONS
Sort by
allows one to select which column on the Results Form will be used to sort the results The Sort by pull-down menu allows selection of either RD #,  Date, Title or Remarks. Results will be sorted  in ascending order within the selected column. Note that if no sort criteria is entered, results are returned in the RD # order.

 Max Records allows one to limit the maximum number of results that will be returned. The default is 25.
