ITHACA, N.Y. (AP) — The biggest collection of material about the Velvet Underground now is housed at Cornell University. Author and collector Johan Kugelberg donated 25 boxes of albums, unreleased recordings, handwritten lyrics and rare photos to Cornell’s Division of Rare and Manuscript Collections. One of the items is an oversized poster for “The Velvet Underground and Nico” that’s believed to be the only existing copy. The collection is being cataloged, but then it will be accessible to the public and to researchers for free.
