Results are reported from two surveys designed to detect fast pulsars - one carried out at 390 MHz using the 92 m telescope at Green Bank, and the other done at 430 MHz with the 305 m Arecibo antenna. Twenty-five new pulsars were discovered. Six pulsars were detected with periods under 300 msec, but none was seen with under 100 msec. One of the new pulsars, PSR 1855 + 09, has a period of 5.362 msec and is a member of a binary system with orbital period 12.3 d; it is the third millisecond pulsar and the sixth binary pulsar known. The 1.5 msec pulsar PSR 1937 + 21, was detected at Arecibo. The two surveys place strong upper limits on the population of pulsars with periods of 10-100 msec in the Galaxy. 33 references.
