Ephemeral films

There are many ephemeral films, i.e. recordings that weren't officially intended as long-lasting cultural works, that have nonetheless been uploaded to archive.org.

They are collected in the collection.

Some of the sub-collections within that include:
 * -- a selection (currently just over 1,500) from a much larger set collected by Skip Elsheimer.
 * -- around 300 historical videos about San Francisco, associated with the website http://www.shapingsf.org
