OCLC bases its agreements with organizations on a highly flexible partnership model. There is no one-size-fits-all approach to building a bibliographic infrastructure. The terms of such an arrangement are determined by the resources and the requirements that are available to the partner in question. In the case of some partnerships, the management and support of the services have been completely outsourced. While in other cases, organizations with the resources and skills available in-house opt to operate completely autonomously. On agreeing to partner with one another, OCLC and the organization consider a range of flexible service options and determine the terms under which to collaborate.
