The Vinland Map, dated to about A.D. 1440 - at least fifty years before Columbus landed in the Americas - is a unique map of the world that shows an outline of the northeast American coast and a legend describing its discovery in about 1000 by Leif Eiriksson, the Norseman from Greenland. The map was published by Yale University Press in 1965 and generated an enormous amount of debate. Chemical analysis of the ink later suggested that the map might be a forgery, but recent appraisals of both scientific and humanist evidence argue that it is indeed authentic. Now, on the thirtieth anniversary of its original publication, here is this classic of historical cartography in a new edition. It reprints unaltered the original text on the Vinland Map and an account of Friar John of Plano Carpini's mission to the Mongols from 1245 to 1247 (the Tartar Relation), with which the map had at some stage been bound. To this have been added a new introduction by George D. Painter, sole survivor of the original team of editors, who discusses the verification of the map's authenticity; a new essay by Wilcomb E. Washburn, director of the Smithsonian's American Studies Program, on the map's provenance and scientific testing; and a new discussion of the map's compositional and structural aspects by Thomas A. Cahill and Bruce H. Kusko, of the Crocker Historical and Archaeological Projects at the University of California, Davis. There is also an account by the rare-book dealer Laurence C. Witten II, who died while this new edition was in preparation, of his acquisition of the map in 1957.

Over the past few decades there has been a major shift in research methodology – away from technicist to more contextual and pragmatic approaches. This is reflected in a greater emphasis on interdisciplinary and applied research skills, the concurrent use of qualitive and quantitative methods, and more sophisticated understanding of the epistemological grounding research.

Research in Practice incorporates these new trends while also providing comprehensive coverage of the full range of established research approaches and techniques.
