Digital Formats
The Digital Formats Web site provides information about digital content formats, including files, underlying bitstreams and encodings, and "wrappers". The site provides information about media-independent ("intangible") formats but not about media-dependent ("tangible") formats. This resource is intended to support both strategic planning and individual selection decisions regarding digital content and its preservation at the Library of Congress. As time passes, the site will offer an ever-increasing inventory of information about current and emerging formats that are promising (or not promising) for long-term sustainability.

Archive Ingest and Handling Test (AIHT)
The Archive Ingest and Handling Test (AIHT), is designed to identify, document and disseminate working methods for preserving the nation's increasingly important digital cultural materials, as well as to identify areas that may require further research or development. The AIHT is part of an initiative, led by the Library of Congress, to build a network of preservation partners through the National Digital Information Infrastructure and Preservation Program (NDIIPP).
