Reviewers do an important but often underappreciated job in the current publication system. To recognize their invisible and usually unpaid efforts, journals often gratefully publish the name of their reviewers by end of the year. From the perspective of reviewers, these “honorable mentions” are nice, but still somewhat scattered and disconnected.
The online network “publons” offers a more personalized approach of earning credit for reviewing. Once you have created an account, you can forward the “thank-you-for-reviewing”-mails that are automatically generated by submission systems after completion of the process. The information will be verified and added to your profile, thus recording your personal history of peer reviewing. This can be helpful to document your services to the community, e.g. in application processes.
