This quick overview (from Cliff's no less!) points out that about 15% of all galaxies are spiral galaxies. http://www.cliffsnotes.com/WileyCDA/CliffsReviewTopic/Galaxies-Types-and-Classifications.topicArticleId-23583,articleId-23570.html There's some more very nice information at: http://www.nasa.gov/worldbook/galaxy_worldbook.html Hope this is helpful! --Bill Pardue Arlington Heights Memorial Library http://www.ahml.info Librarians--Ask Us, We Answer!
