API

The Internet Archive has a number of APIs available for interactions with the collections.

A READTHEDOCS site exists here: https://archive.org/services/docs/api/index.html#

One obscure (but useful) one is https://archive.org/services/img/ which if followed by an item identifier, will provide the thumbnail for the item.

Another obscure one is https://archive.org/serve/{identifier} which seems to be an alias for https://archive.org/download/{identifier} (that provides a directory view of the files in an item)
