TIME & AGAIN: Over a decade before John Lennon was shot outside the Dakota, Jack Finney used the landmarked building as the backdrop for this fascinating 1970s scifi novel, in which hero Si is able to time travel from the contemporary time to New York City in 1882 thanks to a secret government project. There, Si stumbles upon a blackmail scheme and gets involved in an alleged murder, all while falling deeply in love with a 19th century lass. The story's fun, but the time trip's even better, and the novel's peppered with photos and drawings dating back to the 1880s.
