How to add personal notes for each literature in EndNote?

Adding personal notes to individual references within EndNote is a straightforward and essential feature designed to facilitate personal annotation and comprehensive analysis of literature. This capability is integral to effective reference management and scholarly writing workflows. Users primarily utilize the dedicated "Notes" field within a reference record to enter their personal comments, critical insights, or summaries directly associated with that specific piece of literature. EndNote preserves any formatting applied within this field, and these notes are included when exporting references to Rich Text Format (RTF). Alternative methods involve creating custom fields tailored to specific note-taking requirements or attaching supplementary files such as PDFs or documents to the reference entry, which can also contain personal annotations. To add notes using the standard field, open the desired reference record within your EndNote library. Navigate to the "Notes" section (often labeled "Researcher Notes" or "General Notes") within the reference window. Enter your personal annotations, comments, or summary text directly into this field. Alternatively, establish a custom field via Preferences > Custom Fields if specialized categorization is needed. The newly entered notes are automatically saved when you close the reference record or move to another entry.
