Ask, and ye shall receive.... the good folks at OCLC contacted HNN to let us know that there is a downloadable spreadsheet version of the Top 1000 list here for anyone who wants to create their own checklist. I'm still hoping someone will turn it into a web-test. They also posted a list of almost two hundred"runners up" who were close to the threshold: the original list stops with a book held in 5074 libraries; this list goes down to 4693. And history came out really well in this set:

• Barbara Tuchman's Guns of August (#1007, so close!), so we can add WWI to the list of wars with some coverage.
• C.W.Ceram's history of archaeology, Gods, Graves and Scholars made #1017 (and may be the only historiography on the list).
• David McCullough's Truman made #1046, making him the only living historian to appear twice
• Francis Parkman's France and England in America was #1065; combined with McCullough, substantial additions to the US history literature. C. Vann Woodward's Strange Career of Jim Crow (#1119) and Zinn's People's History of the United States (#1135) were pretty notable omissions from the original list, too.
• Elie Wiesel's Night finally showed up (#1068), which gives a little more balance to the Holocaust material.
• Irving Stone's biography of Michaelangelo, The Agony and the Ecstacy brings the art and art history categories together at #1084.
• Plutarch gets another one in, this time Moralia (#1104).
• Henry Adams' Mont-Saint-Michel and Chartres wasn't far behind (#1107) (though it wasn't far ahead of Douglas Adams' Hitchhiker's Guide to the Galaxy (#1109), either).
• John K. Fairbank's United States and China (#1117) is a very welcome addition to the Asian history category.
