EndNote X4 adds these features:
Import and create new records from PDF files. Whether you are importing a single file or a folder of PDF files, EndNote uses metadata and DOI information to create a new reference and attach the source PDF. Basic bibliography information will be added automatically for most journal articles, conference proceedings, conference papers, and reports.
Search the contents of attached PDF files. You will find a new option on the field list to search PDF files separately, or in combination with the reference data.
Create new groups by comparing, combining or suppressing existing groups. The new smart groups are updated dynamically as your library grows.
Transfer up to 10,000 references between the desktop and EndNote online to share online groups with other EndNote users. Shared groups are now included when you Cite While You Write from EndNote online.
Edit references when comparing duplicates—copy/paste and save changes in the side-by-side view.
Cite While You Write new features include:
Add hyperlinks between in-text citations and the bibliography reference in Microsoft Word using any journal style.
Use expanded functionality when editing citations—track usage and more.
Meet the complete APA 6th style requirements including specific handling of references with eight or more authors, hyphenated first names and DOI data.
Improved footnote handling for the Chicago Manual of Style and similar footnote-based bibliographic styles.
Traveling Library enhancements recognize references when sharing Microsoft Word documents for better collaboration.
Get a quick citation report of references cited in a Microsoft Word document with a new auto-group in the EndNote library.
