Book excerpt: This book is based on a series of informative interviews with a number of music librarians working for different leading symphony orchestras and opera companies throughout the world. In these interviews, librarians share with the readers what kind of professional skills, knowledge and personality that are required to supply music to the performers onstage, as well as information to these world-famous performing arts organizations. Interviewees also discuss in details about their professional lives, i.e., including their personal stories and working relationships with various legendary conductors and star soloists, e.g., Claudio Abbado, Simon Rattle, James Levine, Donald Runnicles, Bernard Haitink, Zubin Mehta, Sir Colin Davis, etc. Via the interviewees’ stories, one can also get a glimpse of the different inside operations and the unique management styles behind the backstage of these internationally renowned performing arts organizations. There are fourteen conversations including interviews with the Chief Librarian at the Metropolitan Opera and the Orchestra Librarians at the San Francisco Ballet, the Berlin Philharmonic, and Israel Philharmonic Orchestra.
