Citation managers are database managers which allow you to create your own database with the bibliographic references you gather during your research work. Most citation managers make it possible to:
- download references automatically from library catalogues and bibliographic databases (but some references have to be entered manually anyway);
- search for references, sort them, eliminate duplicates;
- create independent bibliographies or insert references in a text while you are writing. You can choose between many different styles, change the style during the writing process, and produce automatically the bibliography at the end of your dissertation.
Using a citation manager will allow you to save a lot of time, to avoid tedious and uninteresting tasks, to better the quality of your bibliographies, and to concentrate on research and writing.
