4. Insert keywords

When importing references from a source, the keywords from that source are imported into the "keywords" field. EndNote provides an option to scan the abstract or other fields, and in this case add keywords already existing elsewhere in other references.

However, depending on the source, different keywords for the same concept are implemented. We therefore find several words here, or even a categorization (administration & dosage for interferons, taken from the Embase database, for example).
