Metadata?
Exact match: - XML API (need to mark up)
Needs evaluation: - Metadata Search - REST API
Formatted reference?
Exact match: - Simple Text Query form - XML API (some limitations)
Needs evaluation: - Metadata Search - REST API
Needs evaluation:!- not always exact !
- will return approximate results!
- will also return other stuff !
Good for: !finding approximate results, working with messy data, evaluating matches on your own!
Exact:!- field-by-field match!
- match or no match at all!
Good for: !auto-populating lists of references!
Simple Text Query form!
XML API!
• Match references to DOIs • Login required but most
queries are free • Good for reference linking
HTTPS
