Abstract
A new polarimeter called AnyPol has been used at Limber Observatory for 4 y r to monitor annually the broadband linear polarization of a sample of brig ht northern Be stars. This is the fourth report on a program started in 198 5 at McDonald Observatory and the first one to come entirely from the new i nstallation. Although no variability was detected at the 3 sigma level duri ng the current reporting period, analysis of the full 13 yr data set is beg inning to reveal hints of long-term variability that may provide clues for understanding the Be phenomenon.
