From their site: CatalogWS is a Web API for dynamically querying information from the NCSU Libraries Catalog (North Carolina State University). This API supports a variety of applications that repurpose catalog data outside of the native catalog interface.
The following is a list of SDKs from our SDK directory that matched your search term. Though your definition of an SDK may differ, in our world, we define SDKs as platform- specific tools for consuming existing APIs of the sort we list in our API directory. For example, the Ruby SDK for consuming the Twitter Ads API.
