A new polarimeter called AnyPol has been used at Limber Observatory for fouryears to annually monitor the broadband linear polarization of a sample ofbright northern Be stars. This is the fourth report on a program started in1985 at McDonald Observatory and the first one to come entirely from the newinstallation. Although no variability was detected at the 3-sigma level duringthe current reporting period, analysis of the full 13-year data set isbeginning to reveal hints of long-term variability that may provide clues forunderstanding the Be phenomenon.Comment: 25 pages including 17 tables; 17 figures; aaspp4 style; accepted by PAS
