By now you should be able to confidently use EndNote 20 to improve your writing, through the efficient management and formatting of the sources you gather as part of your research projects.
Top tips to keep in mind as you move forward:
Know and understand the protocols of your referencing style thoroughly. Although EndNote 20 and other reference management tools save you time, your familiarity with the style or styles used in your school or college will enable you to check the accuracy and consistency of the citations in your document every time, as well as spot inconsistencies if and when they appear - and they will!
"Messy data in, messy data out" - the quality of the information in your EndNote 20 library will be reflected in your document. Make time to review the accuracy and integrity of the bibliographic data which make up the references in your library, so that your citations and bibliographies are clean and accurate.
Be mindful of your "digital hygiene" and use the File > Compressed Library command to make regular backups of your library - just in case of unexpected hardware or software issues, which could potentially compromise your library.
