Small enhancements made to WorldCat Search API

There was a small set of enhancements made to the WorldCat Search API last night. Nothing too earth-shattering, but a few nice little things to help your apps and mash-ups work smoother, faster, better:

  • The LCCN is now available for default queries. (This index will be available using the Exact relation.)
  • Now you can use the JSON format option for library holdings without a record identifier.
  • Dublin Core and MARC XML format records are now produced from a newer version of the OCLC Crosswalk Web service--an experimental Research project/prototype.

In terms of the Crosswalk, no changes are expected to the format of these records, but the infrastructure change will help improve the API's stability and performance even more.

There are no Profiles matching the configured list.
