The next few decades saw rapid expansion for the school and its programs. By 1976, William Mitchell had outgrown the space at St. Thomas and required larger facilities. The administration successfully purchased the building at 875 Summit Avenue, a former Catholic secondary school called Our Lady of Peace. In 1974, William Mitchell had launched its flagship legal journal, the "William Mitchell Law Review". This journal later formed half of the merged Mitchell Hamline Law Review. By 1980, William Mitchell began offering traditional daytime classes and the option of full-time enrollment. In 1990, the school completed work on its campus additions, which included a new classroom building and the Warren E. Burger Law Library. The library houses WMCL's collection of nearly a half-million volumes, affords electronic access to thousands of additional documents, and provides extensive study space. Justice Sandra Day O'Connor accompanied Chief Justice Burger to the dedication. Continuing its tradition of attracting adjunct faculty from the state and federal bench, Donald Lay, Paul Magnuson, Donovan Frank, Edward Toussaint, Jr. and others have taught and continue teaching at WMCL. In 2010, William Mitchell launched an intellectual property law journal, Cybaris.
