Does this skill require an API key for Harvard LibraryCloud?

No, the Harvard LibraryCloud and PRESTO APIs are public and do not require an API key, though they do require a User-Agent header which this skill provides automatically.

Are there any usage limits for the Harvard Library API?

Yes, the API has a rate limit of 1 request per second or 300 requests every 5 minutes. This skill's implementation includes logic to manage these limits and prevent lockouts.

Can I download full-text books with this skill?

No, this skill retrieves bibliographic metadata and catalog records. While it can identify if an item is available online, it does not download or bypass paywalls for copyrighted digital files.

What metadata formats are supported for record retrieval?

The skill supports JSON and XML via LibraryCloud, and provides access to raw MARC, MODS, and Dublin Core (DC) formats through the PRESTO lookup service for specific HOLLIS IDs.
