Pulsars discovered since the end of the EGRET mission coincident with unidentified high-energy gamma-ray sources are prime targets for AGILE. Both general surveys and targeted observations have been successful in finding energetic young pulsars in the plane of the Galaxy. For the latter, hard X-ray imaging followed by deep radio searches of X-ray sources is a proven route. High-resolution Chandra X-ray imaging has discovered several asymmetric pulsar wind nebulae associated with apparently variable gamma-ray sources along the Galactic plane. The unidentified sources at intermediate Galactic latitudes, with their much larger error boxes, make new X-ray studies impractical. A radio search of a number of these sources using the Parkes multibeam system has resulted in the detection of several new binary pulsar systems. Whether these are potential gamma-ray emitters has yet to be determined.
