Controlled libraries, also known as configuration-controlled libraries, are used to store and manage intermediate baselines. These baselines are versions of the software at various points in the development lifecycle. By archiving these baselines in a controlled library, teams can ensure that all changes are tracked, and specific versions can be retrieved when needed for further development, testing, or rollback purposes. This practice is essential in maintaining configuration management and ensuring the integrity and traceability of software versions.
