Jeff,
The USGS supported the collection of the information published on the APSRS
CDs. The information has not been updated since around 2000. I have a
database dump of the information, but suspect most of the contents would be
of little value today.
There is an effort from the American Society of Photogrammetry and Remote
Sensing - the similar acronym to APSRS - to maintain an online, keyword
searchable inventory of aerial sources. This free service went live spring
of 2016 and contains references to several million frames of photography
dating from the 1920s onward. The system is not like USGS' Earth Explorer
as so many sources do not have frame-based geographics. The ASPRS Aerial
Data Catalog is located at http://dpac.asprs.org/
As part of the volunteer team that developed and maintains this service,
feel free to shoot me questions. Also, we are always looking for folks to
contribute metadata to further advertise their holdings as the system
really is a referral means to discovery sources of aerial photography and
to provide the contact information for the sources.
Best,
