Sitemap Seen as a natural fit for the NDP initiative, SirsiDynix has entered into a business and technical partnership with GeoLib and is providing funding to support the on-going success of the project. To date, this includes funding for annual database updates, data validation through exhaustive manual review phases, development of pre-set geographic customer market areas for all public library outlets in the United States, and finally, integration at the library outlet level between NDP's aggregation of transaction-level circulation data and the GeoLib Geographic Information System (GIS) interface.
