Revisionism and professional ethics

Staff at the Alliance Israelite Universelle library in Paris found themselves confronted with an ethical dilemma when a known Holocaust denier began to pay repeated visits to its reading room. His visits challenged the library’s visitor policy and raised a number of questions about the relevance of a professional code of ethics for librarians in such a situation that was difficult to predict. Should we let a Holocaust denier use our collections? Could we tolerate his presence and offer him the same service as our other readers?
