Recommended Format Specifications are hierarchies of the physical and technical characteristics of creative formats, both analog and digital, which will best meet the needs of all concerned, maximizing the chances for survival and continued accessibility of creative content well into the future.
There are two primary purposes of the specifications. One purpose of the specifications is to provide internal guidance within the Library to help inform acquisitions of collections materials (other than materials received through the Copyright Office). A second purpose is to inform the creative and library communities on best practices for ensuring the preservation of, and long-term access to, the creative output of the nation and the world.
Six broad categories of creative output, and particular format specifications in descending order of preference.
- Textual Works and Musical Compositions
- Still Image Works
- Audio Works
- Moving Image Works
- Software and Electronic Gaming and Learning
