dc.descriptionWe present results from a preliminary analysis of a recently-completed, multicolor imaging survey of nearby, early-type barred galaxies in the field, carried out with the WIYN telescope and supplemented with archival HST images. This forms a reasonably complete sample of nearby, bright, barred S0 and Sa galaxies in the field. The excellent seeing provided by WIYN allows us to examine the galaxies for central features such as circumnuclear rings and secondary bars; we find some evidence for dust lanes within secondary bars. The most striking results is the high frequency of double bars: our analysis suggests that at least $\sim 20%$ of barred S0-Sa galaxies possess secondary bars}. We also find an excellent candidate triply barred galaxy: NGC 2681.
