Governments are not the only ones who censor information. For example, when the history department at Middlebury College did not allow professors to accept Wikipedia as a source in papers, some said it was censorship. This was because the department was telling professors (who usually have academic freedom) what works they should or should not accept. Sometimes, a group or a website will not allow some facts, articles, and pictures that they do not think should be seen. There is much debate over the difference between censorship and editing, that is, deciding what should or should not be published.
