Michael Palumbo, author of "The Palestinian Catastrophe: The 1948 Expulsion of a People from Their Homeland", reviewing the first edition of Morris's book on Palestinian refugees, criticises Morris's decision, which Palumbo thinks characteristic of Israeli revisionist historians generally, to rely mainly on official, "carefully screened" Israeli sources, especially for radio transcripts of Arab broadcasts, while disregarding unofficial Israeli sources such as transcripts from the BBC and CIA, many of which point to a policy of expulsion. He says Morris failed to supplement his work in Israeli archives, many still classified, by U.N., American, and British archival sources that Palumbo considers objective on such issues as IDF atrocities, as well as oral testimonies of Palestinians and Israelis, which can be reliable if their substance can be independently verified. Palumbo says:Morris' regard for documentation is indeed commendable, were it not for his tendency to choose sources which support his views, while avoiding those document collections which contain information inconsistent with his principal arguments. His decision not to use the testimony of Israeli veterans is unfortunate, since some of them have spoken candidly about Israeli atrocities and expulsion of civilians at Deir Yassin, Lydda–Ramle and Jaffa.
