PAN AMERICAN UNION ANNEX - Glass negative photogrpah. Public domain.

The Harris & Ewing, Inc. Collection of photographic negatives includes glass and film negatives taken by Harris & Ewing, Inc., which provide excellent coverage of Washington people, events, and architecture, during the period 1905-1945. Harris & Ewing, Inc., gave its collection of negatives to the Library in 1955. The Library retained about 50,000 news photographs and 20,000 studio portraits of notable people. Approximately 28,000 negatives have been processed and are available online. (About 42,000 negatives still need to be indexed.)

This is another AI-assisted collection, this time it features 20K+ images of manors. A manor is a large country house with lands, the principal house of a landed (country) estate. This collection took about 15 minutes to make, including adding about 18,000 relevant images as "manors" and removing portraits of people with "Manor" last names. Of course, image recognition was already done before and that process required much much longer time and machine resources.
