Legal scholarship is tracked by various means and for various purposes. It is important to make sure you are associated with all the work you produce. This will make it easier for employers to access your scholarly impact and for colleagues to find appropriate collaborators.
The University of Illinois maintains a database of scholarship by its faculty to facilitate collaboration and to celebrate their productivity called Illinois Experts.
HeinOnline is also endeavoring to correctly associate authors with their work, maintain a list of those works and the subsequent citations thereto.
Other disciplines use other metrics so if your work involves an interdisciplinary component it is worth investing in those systems.
