To access SDC, you must first create a LSEG Workspace account (formerly Refinitiv). After you have done that, please email lippincott@wharton.upenn.edu to request access. The Lippincott librarians will confirm that SDC access has been added to your account. Once your account is enabled, you can enter SDC in the top search bar in LSEG Workspace and select the SDC app. 

Some SDC data is available via WRDS (see access details) under Thomson/Refinitiv.
