A handy way to keep track of your publications under a single, common identifier is ORCID (Open Researcher and Contributor ID), a free open-source registry that gives authors a unique identifier which can then be linked to other professional accounts and used on future work and research to ensure a common connection between the author and the work.
For more on author impact and citation tracking, see the guide listed below.
The Scholarly Publishing & Academic Resources Coalition (SPARC) is an alliance of academic and research libraries organized through the Association of Research Libraries (ARL). Their Author Resources page includes the Author Addendum as well as more information about copyright and open access as it relates to academic researchers. See PDFs below!
Another useful addendum tool is the Scholar's Copyright Addendum Engine, created by Creative Commons' Science Commons project. This site allows you to create a PDF personalized with the name of your article and the type of copyright agreement that applies, which differ mostly in terms of the embargo period preferred and ability of others to reuse your work.
