搖滾歌王和詩人鮑勃·迪蘭的資料大全，厚達823頁，不僅收入瞭他所有作品和演齣的資訊，也包括那些對他産生過重大影響的詩人、作傢、歌手和作麯傢們的資料——如迪蘭·托馬斯、威廉·布萊剋和威廉·卡洛斯·威廉斯等大詩人，以及不同時代評論傢對他的看法。但書中又說，迪蘭所經曆的太廣、太深，也太長久，任何一本書絕難包容。

The most encyclopedic sourcebook on one of the 20th century's most important artists, Keys to the Rain: The Definitive Bob Dylan Encyclopedia completely chronicles this music icon's recorded work. Discussions of all of his officially released albums and collaborative efforts, including year of release, record company, serial number information for all formats (LP, CD, and cassette), track list, musicians, and descriptive analysis of its place in Dylan's career are provided. In addition, it offers critical and historically detailed entries on each of the songs that Dylan has recorded or performed in more than four decades of touring, including composer information, and the album on which the song appeared. Completing this reference are detailed biographical sketches of more than 100 musicians, songwriters, and other individuals associated with Dylan, and a selected list of films in which he has been involved.
