This document (version 1.0) identifies the file formats (either Recommended or Acceptable for Transfer) that Library and Archives Canada (LAC) will be supporting within the Trusted Digital Repository (TDR). Formats are identified for 11 content categories including audio. The register is not simply a list, it also includes guidelines on file quality and some explanation on file and codecs types. It is concerned with media-independent content; that is digital content that is managed as file types and is not inextricably linked to a physical storage medium.

The document is quite readable because it is intended for a broad audience including the public, academic and private sectors. It is a good example of institutional policy. Its evaluation criteria methodology, which incorporates diverse criteria from the US, UK, NL and Canada, demonstrates a useful approach for other institutions.
