In June the Library of Congress released Recommended Formats Specifications to assist in its acquisitions process. These recommendations were developed with the idea of long-term preservation in mind and take on the analog as well as the digital. They cover six categories of creative works: Textual Works & Musical Compositions, Still Image Works, Audio Works, Moving Image Works, Software & Electronic Gaming & Learning, and Datasets/Databases.
While the primary purpose of these recommendations is to provide internal guidance at the Library of Congress, it will also serve as a best-practices guide to the library and related communities to help ensure long-term preservation of creative works. And do bear in mind that while these are recommended formats, it doesn't necessarily mean that other formats should be excluded. It merely identifies those that have the best potential for long-term access.
