New content and science functionality of the NASA/IPAC ExtragalacticDatabase (NED) are presented. New content includes 230,000 objects from the SWIRE catalog (2008MNRAS.386..697R), 100,000 Chandra Source Catalog v1.1 objects (2010ApJS..189...37E), 13,000 objects in the Extragalactic Distance Database (EDD-2009AJ....138.1938C), 6,000 objects and redshifts from the WINGS survey (2009A&A...495..707C) plus tens of thousands of objects reported in the current refereed literature. The NED-D Distance database has been updated to contain 36,000 distances for 9,000 galaxies. The searchable Galaxy Classification service released in January 2010 continues to grow with past and current published data offering Galaxy Morphologies in both optical and radio regimes, Activity and Spectral Types, Luminosity Classes and more. New functionality is introduced that enables users to control what parameters are returned for objects selected with constraints on galaxy classifications. In addition to selection or deselection of basic source parameters such as coordinates and redshift, the Customized Output feature also enables users to extract detailed measurements such as multi-wavelength photometry and diameters (as available), all from a single query. The resultant data table lists each requested parameter in a separate column, one row for each object in the sample, making further analysis more convenient. In the coming year this capability will be expanded to provide more dynamic and flexible options, and it will be extended to other types of NED queries. Hardware and software modifications will also allow more frequent updates of the NED database. Researchers are encouraged to visit the NED exhibit booth at this meeting for a demonstration and further information. NED is operated by the Jet Propulsion Laboratory, California Institute of Technology, under contract with the National Aeronautics and Space Administration.
