How to use Second World War finding aids

1. Zoom to your Area of Interest

Browse by Map to your general area of interest and click on 'See finding aids in this area'.

2. Search Results

You are presented with a list of all the missions, or sorties, linked to the grid square of 10-minutes of latitude and longitude in which your area of interest is located.

You can order this list chronologically by clicking on 'Date'.

To examine the finding aids in detail, you will need a website subscription.

3. Examine a Finding Aid

Right-click on a mission of interest and select 'Open link in new tab'.

A new tab will open, showing our record for the selected mission. Since missions often covered more than one location, there may be more than one page. A thumbnail for each page is shown. The map on the right-hand side of the page shows the grid squares covered during the mission.

Click on a thumbnail, then click 'Zoom Image'.

4. Identify a Photograph

Zoom and pan the finding aid until you find your area of interest. The locations and coverage of photographs are shown by boxes or strips drawn on the map. See if these fall over your area of interest. Your area of interest may appear on more than one page, so remember to check all of the thumbnails for each mission.

The photograph frame number is shown in the box. Sometimes frames are only shown at intervals along a strip. In this example, the centre of Utrecht is covered by frame 4046 from mission US7/1983.

5. Mission Data

Information about the mission is recorded in a data box on the finding aid.

This gives the title and date of the mission, and sometimes shows the time of the first photo run. Occasionally, the name and rank of the pilot or navigator of the aircraft is recorded.

The frame numbers of the photographs taken during the mission are shown, along with the focal length of the camera lens, the aircraft flying height and photograph scale.  Image quality (IQ) is noted, graded from A (best) to C (poor).

6. Order a Photograph

Once you have found photographs of your area of interest, you can order copies to be digitised.

Record the frame numbers of the photographs you require in the notepad area. Then click 'Order Images'.

Our online order form will open in a new tab. You can select the resolution of copy you require, provide your contact details and tell us how you wish to use the image before submitting your order.

7. Can't identify the right image?

If you are unable to decide which frame covers your area of interest, we offer 72ppi Research Copies. These allow you to check the coverage and quality of a photograph before ordering a high-resolution copy.

The finding aids may not always be 100% accurate, so we recommend that you also order copies of the frames before and after the one you have identified, to make sure you cover the area you want.

8. No cover of your Area of Interest

If the finding aid shows no photography of your specific area of interest, close the tab and return to the page of search results. Select another mission from the list and repeat steps 3 and 4.

Once you have examined all of the relevant finding aids, you have completed your search.
