Archive-It recently introduced an OAI-PMH metadata feed for all Archive-It collections. This feed has been submitted to the OAIster catalog. Our feed has been harvested and you will see hits from Archive-It collections in your search results.
We are also planning to integrate an SRU protocol in our search engine very soon. The Archive-It team is very excited about providing new ways for our partners and their patrons to be able to access their Archive-It collections.
