Authors may choose to restrict access to the full text of their thesis or dissertation to protect sensitive information or because they have applied for a patent based on their work. In such cases, readers may access a work only after a designated period of time (the embargo period). At Northeastern, the maximum embargo permitted is two years. You may find that dissertations and theses from other institutions have embargoes of different lengths or have other restrictions. But in general, even while the full text is embargoed, the citation and abstract is still made available to researchers.
