Why is "Moose: Chapters From My Life" trending?

Wikipedia Overview

Moose: Chapters From My Life is the 459-page autobiography by the Academy Award-winning songwriter Robert B. Sherman. "Moose is a collection of fifty-four autobiographical short stories, arranged in such a way as to express a larger narrative." The book was edited by Sherman's younger son, Robert J. Sherman, who also provided the general layout, cover art and graphic design for the book. Other than certain pages in the "My Time" photographic sections of Moose, the majority of the book, including its innovative arrangement of chapters, was created during the author's lifetime and under his personal supervision. Moose was published by AuthorHouse Publishers of Bloomington, Indiana, in association with AuthorSolutions, Penguin Random House Company affiliates. First publication of the work occurred posthumously, on November 26, 2013. The majority of short stories which comprise the book, were written between 1993–2004 with one or two stories having been known to exist as early as 1945. Although early "mock-up" versions of the book were circulated among Sherman's close friends and members of his family in 2004, according to the editor's introductory chapter, "About Moose", mass publication had to be delayed "for reasons too cumbersome to delve into here." Both the book and its author were credited in the 2013 Walt Disney film release, Saving Mr. Banks which starred Academy Award–winning actors Emma Thompson and Tom Hanks. Actor B. J. Novak portrayed a young Robert Sherman in the film. Several scenes from the film drew direct inspiration from Moose. This was done with the author's consent.
