Effective February 27, 2017, the API methods GetPartEndNote and GetTitleEndNote will be removed. In addition, the BHL data exports that used the related format have already been removed. The removed BHL API methods and data exports will soon be replaced by methods and exports that use the RIS format, which is supported by a wider range of bibliographic reference managers. Thank you for your patience as we work to implement the RIS-based exports and API methods. If you have any questions, please submit them via our feedback form. You can learn more about our developer tools and APIs here.
