DOCLINE primarily uses Google Accounts for secure user authentication. NLM suggests each user set up an individual Google account based on their existing work email address. Users at federal libraries or NIH-federated research institutions may have other alternate methods available.

To set up your Google account (without Gmail), please follow these steps. To link your Google account to DOCLINE, use the ‘Apply Now’ button at https://www.docline.gov, and supply your Google account email address and your LIBID.
