to piece together war histories. Despite these limits, wars are some of the most studied and detailed periods of human history. Military historians have often compared organization, tactical and strategic ideas, leadership, and national support of the militaries of different nations. In the early 1980s, historian Jeffrey Kimball studied the influence of a historian's political position on current events on interpretive disagreement regarding the causes of 20th century wars. He surveyed the ideological preferences of 109 active diplomatic historians in the United States as well as 54 active military historians. He finds that their current political views are moderately correlated with their historiographical interpretations. A clear position on the left-right continuum regarding capitalism was apparent in most cases. All groups agreed with the proposition, "historically, Americans have tended to view questions of their national security in terms of such extremes as good vs. evil." Though the Socialists were split, the other groups agreed that "miscalculation and/or misunderstanding of the situation" had caused U.S. interventionism." Kimball reports that: Of historians in the field of diplomatic history, 7% are Socialist, 19% are Other, 53% are Liberal, 11% are None and 10% Conservative. Of military historians, 0% are Socialist, 8% are Other, 35% are Liberal, 18% are None and 40% are Conservative. Online resources People interested in military history from all periods of time, and all subtopics, are increasingly turning to the Internet for many more resources than are typically available in nearby libraries. Since 1993, one of the most popular sites, with over 4000 members (subscriptions are free) has been H-WAR, sponsored by the H-Net network based at Michigan State University. H-War has six coeditors, and an academic advisory board that sets policy. It sponsors daily moderated discussions of current topics, announcements of new publications and conferences, and reports on developments at conferences. The H-Net family of lists has sponsored and published over 46,000 scholarly book reviews, thousands of which deal with books in military history broadly conceived. Wikipedia itself has a very wide coverage of military history, with over 180,000 articles. Its editors sponsor Wikipedia:WikiProject Military history and encourage readers to join. Military and war museums Military museums specialize in military histories; they are often organized from a national point of view, where a museum in a particular country will have displays organized around conflicts in which that country has taken part. They typically take a broad view of warfare's role
