GPO has been developing partnerships with Federal depository libraries and other Federal agencies to increase access to electronic Federal information since 1997. With an increasing amount of Federal information available electronically, partnerships ensure permanent public access to electronic content and provide services to assist depositories in providing access to electronic material and in managing their depository collections. These partnerships also allow GPO to take advantage of the expertise of Federal depository librarians and the services they have developed. While FDLP partnerships will vary based on the type of project, partnerships generally fall into three categories. However, partnerships are not limited to these categories, and GPO will consider partnership proposals that fall outside of these categories.
