For referencing material BU uses a version of Harvard - guidance on using this is available in the Referencing - BU Harvard LibGuide.
Law students use OSCOLA for legal referencing. Guidance is available on citing in our guides Referencing - UK and EU Law, and Referencing - International Law. Non law students should only use these guides for examples of how to reference legal materials that are not covered by Harvard.
Psychology students use the American Psychological Society system, APA
Most databases give you options to save, email or print your results, or to export them to bibliographic management software.
EndNote is the software that is supported by BU - there is a desktop version and also a web version which allows you to access all your references both on and off campus.
