The service provides images of book covers for publications from New Zealand as a way to support the country's libraries and promote its publications in catalogs of relevant works. Licensing terms do not allow access by libraries and other users outside New Zealand.
API methods accept queries to identify books and other printed resources as HTTP GET requests providing unique resource identifiers such as ISBN, ISSN, ISMN, or NBD number. If found, the API returns URLs for both full-size and thumbnail images from the namespace http://digital.natlib.govt.nz that can be incorporated in the tag to include the cover image in a catalog web display.
The following is a list of historical changes that were made to this asset. Typically, once an API is published on ProgrammableWeb.com, the data we keep about that asset gets updated over the course of its life. For example, the endpoint or home page of the documentation might change. As a means of enforcing the integrity of our data, every time a non-trivial change is made to the data we keep about an asset, we require the entry of some changelog text before that change can be saved. This way, we have a great audit trail of all activity surrounding the asset. For each asset, the changelogs begins with the moment an asset is approved for publication on ProgrammableWeb. If you spot an error in our data and believe that a record needs to be updated in some way, the ProgrammableWeb team would very much like to hear from you at firstname.lastname@example.org
