If you are involved in scientific or scholarly research, we invite you to join our network of more than 480,000 research professionals worldwide. By joining COS, you will gain access to your own personalized COS Workbench, a customized web tool that allows you to navigate our web site and maximize the many resources available to you through COS.

COS offers three types of memberships that provide a wide range of benefits. The three types of memberships include:

Individuals
Individual researchers in all disciplines are encouraged to join COS free of charge. Researchers use the COS network to find funding, promote their research, track current research activities, and collaborate with peers from around the world. See Benefits to Individuals.

Universities and Research Institutions
Universities and institutions that partner with COS as members join a growing network of more than 700 research facilities around the world. When member institutions contribute information about their researchers, they gain access to COS's powerful administrative tools. These tools efficiently and cost-effectively distribute information for and about researchers, integrating it back into the institutions' operations, enabling them to keep current with research developments worldwide.
