Preservation plan for the Microsoft Live Book data ingested into the DOM system at the British Library (BL) | Preservation format | "JPEG2000 files will be retained for preservation as per the original project specifications...The JP2 files fulfil the role of master file but a lack of industry take-up is a slight concern from a preservation viewpoint. However, the format is well defined and documented and poses no immediate risk." |

Digitization Program | Preservation format | "Our preservation format is JPEG2000 with lossless compression. The preserved image is not processed or reduced in any way after the scanning process. By choosing losslessly compressed JPEG2000 instead of uncompressed TIFF as a preservation format, we will reduce the need for digital storage by about 50%. [...] Through practical tests we have demonstrated that we are able to convert from the JPEG2000 format back to uncompressed TIFF with absolutely no loss of information" |

"Topographical Map Collection " | "Lossless and Lossy formats for web access " | "The digital collection is composed of both georeferenced JPEG 2000 format images and lossless (unaltered) non-georeferenced JPEG 2000 images. JPEG 2000 is a relatively new, yet widely supported image format that offers superior compression performance." |
| Princeton University Library | Princeton UL Digital Collections "Imaging Standards/About" http://diglib.princeton.edu/ ?_xq=html&_xsl=imaging.xsl |
Digital Library (imaging standards) | TIFF Master files with JPEG 2000 derivatives | For the most part, we'll be deriving JPEG2000 images from the master TIFF files. JPEG2000 is a recently-developed imaging standard that is based on wavelet technology. Wavelets allow a great deal of end user functionality (like zooming, panning, etc.), while retaining small file sizes and little loss from a great deal of compression. |
