Publisher Little, Brown has taken the unusual step of withdrawing a book – a history of the creation of the atomic bomb, after four wurthors complained that the book contained passages drawn from their work, uncredited.The author, Brian VanDeMark, 42, said yesterday that he had no comment. In a telephone interview on Friday he said that he was confident that ‘detached readers would find a majority’ of the passages in question to be ‘reasonable paraphrases.’ But he added then that “a minority should and will be reworded or credited in a footnote.”
