ArtScroll's English explanations and footnoted commentary in the Schottenstein Edition of the Talmud are based on the perspective of classical Jewish sources. The clarifying explanation is generally based on the viewpoint of Rashi, the medieval commentator who wrote the first comprehensive commentary on the Talmud. The Schottenstein Edition does not include contemporary academic or critical scholarship. The overall guidelines follow a pattern defined by the late Rabbi Hersh Goldwurm, "a Monsey, N.Y., scholar who died in 1993." The total cost of the project is estimated at US$21 million, most of which was contributed by private donors and foundations. Some volumes have up to 2 million copies in distribution, while more recent volumes have only 90,000 copies currently printed. A completed set was dedicated on February 9, 2005, to the Library of Congress, and the siyum (celebration at the "completion") was held on March 15, 2005, the 13th yahrzeit of Jerome Schottenstein, at the New York Hilton.
