It was built to house and provide permanent access to tobacco industry internal corporate documents produced during litigation between US States and the seven major tobacco industry organizations and other sources.

The JC virus or John Cunningham virus (JCV, not to be confused with Jamestown Canyon virus that bears the same initials) is a type of human polyomavirus (formerly known as papovavirus) and is genetically similar to BK virus and SV40.
It was identified by electron microscopy in 1965 by Zu Rhein and Chou, A map of the genome of JC virus, indicating the position of the tumor antigen genes (red), the three capsid protein genes (green and blue), the agnogene (yellow), and the non-coding control region (NCCR).
14 subtypes or genotypes are recognised each associated with a specific geographical region. A minor African type—Af1—occurs in Central and West Africa.
The major African type—Af2—is found throughout Africa and also in West and South Asia.
