Letter from Thomas Gold to Mr Warren E Preece, Editor in Chief, Encyclopaedia Britannica, 425 North Michigan, Chicago, Illinois Writes to complain about errors in the publication bearing his name in the "Year Book of Science and The Future". His name has been used for material entirely prepared by editorial staff and he considers this unethical, against copyright law and damaging to his reputation as the statements made in the article contradict what he has already stated about pulsars. Did not write or even see article. Would like to submit his original article to a widely circulated journal such as "Science". Has consulted a law firm and they advise him that he has a case however he is writing to Mr Preece in the first instance on how he proposes to deal with the problem. 15 January 1969
