Bob Dylan may have a shiny new Nobel Prize among his mementos, but the job of archiving and preserving the legendary musician’s other treasures has fallen upon 41-year-old Brooklynite Michael Chaiken.

A 6,000-piece collection of Dylan’s belongings, including lyric manuscripts, notebooks, film reels, correspondence and other artifacts, was acquired from the singer by the University of Tulsa and the George Kaiser Family Foundation for an undisclosed sum in March.

Chaiken, an avid Dylan fan, was hired in May to oversee the collection.

Once items get to Chaiken, they are placed in a freezing chamber at a temperature of minus-20 degrees Fahrenheit for 72 hours “ to kill any microbes and bacteria and to make sure there is no contamination,” Chaiken explained.

The items are then placed in a customized vault.

“What surprised me most about the archive was to see all of these alternative lyrics from songs like ‘Maggie’s Farm’ and ‘Subterranean Homesick Blues,’ ” he said. “It brings home the fact that these songs weren’t just pulled out of the sky.”

Here are a few items from the archive:

Tambourine man’s gear

Folk musician and Greenwich Village fixture Bruce Langhorne lost the second and third fingers on his right hand in a childhood accident, which resulted in a unique tambourine-playing style. Langhorne and his tambourine allegedly provided the inspiration for Dylan’s “Mr. Tambourine Man.” The two recorded music together; Langhorne also worked with Joan Baez, Richie Havens and Peter, Paul & Mary.

Leather Jacket

This black leather jacket was worn by Bob Dylan on stage at the Newport Folk Festival in 1965 in Newport, RI — the same night Dylan used an electric guitar, outraging folk-music purists. When he played the tune “Maggie’s Farm,” some audience members booed while others complained loudly about the sound quality.

Handwritten “Chimes of Freedom” lyrics

Written in a Waldorf Astoria hotel room in Toronto while waiting out a lightening storm with a lover, “Chimes of Freedom” went on to appear on Dylan’s 1964 album “Another Side of Bob Dylan.” The song has been covered by many musicians including U2, Bruce Springsteen and The Byrds.

“Highway 61 Revisited” master tape

This reel — which includes handwritten track listings from the album’s producer, Bob Johnston — contains some of Dylan’s most iconic songs, such as “Like a Rolling Stone” and “Desolation Row.” It was Dylan’s sixth studio album and was recorded while he was still under contract with Columbia Records.
