Sound Directions: Best Practices for Audio Preservation establishes best practices in many areas where they did not previously exist. This work also explores the testing and use of existing and emerging standards. It includes chapters on personnel and equipment for preservation transfer, digital files, metadata, storage, preservation packages and interchange, and audio preservation systems and workflows. Each chapter is divided into two major parts: a preservation overview that summarizes key concepts for collection managers and curators, followed by a section that presents recommended technical practices for audio engineers, digital librarians, and other technical staff. This latter section includes a detailed look at the inner workings of the audio preservation systems at both Harvard and Indiana.
