Since 1993, the daily email discussion list H-Urban has enabled historians, graduate students and others interested in urban history and urban studies to communicate current research and research interests easily; to query and discuss new approaches, sources, methods, and tools of analysis; and to comment on contemporary historiography. The logs are open to searches, and membership is free. H-Urban seeks to inform historians on such matters as announcements, calls for papers, conferences, awards, fellowships, availability of new sources and archives, reports on new research, and teaching tools, including books, articles, works-in-progress, research reports, primary historical documents (for example, model ordinances, federal/state/local reports, addresses of city officials), syllabi, bibliographies, software, datasets, and multimedia publications or projects. It commissions its own book reviews. H-Urban has 2,856 subscribers (as of 2012) and is the oldest of the H-Net network of discussion lists.
