Tips for Searching for Historical Images
- Boolean searching is allowed. Simply capitalize the AND, OR, or NOT.
- The search term must be an exact match (except for case) for the term in the title or the description of the image.
- Not enough search results? Try using * as a wildcard or to truncate.
- Try using variant spellings (such as Vice-President, VP, V-P, etc.)
- The titles of the images have a code which lets you know what collection it is from:
|
aas = Astronomers onj = Miscellaneous lib = Library old = Old USNO g = Glass Plates bg1 = Buildings and Grounds 1 |
ref = 26" Refracting Telescope bg2 = Buildings and Grounds 2 onj = Miscellaneous oth = Other Observatories sta = Other USNO Stations sup = Superintendents |
tci = Instruments - Transit Circles clo = Clocks from Time Service 1 clk = Clocks from Time Service 2 ext = Exhibits and Tours LanternSlide = Other Lantern Slides QB and QC = either Cataloged Lantern Slide or Stereocard |
[So for example, an image with the title bg13f.jpg is from the Buildings and Grounds 1 collection, an image with the title
QB82H245no1ST.jpg is either a stereocard or a cataloged lantern slide (in this case, a stereocard).]
- Example search terms include: Venus, telescope, Galileo, Maury
- Still cannot find what you are looking for? Try browsing the collection instead of searching.
