The Recommended File Formats for Long Term Preservation
You have precious family history files, both physical and digital. Have you ever wondered if they are in the proper form for safe, long term preservation? Consider taking a cue from the United State’s oldest federal cultural institution and the largest library in the world, holding more than 158 million items in various languages, disciplines and formats.
According to their announcement today the Library of Congress today released “a set of recommended formats for a broad spectrum of creative works, ranging from books to digital music, to inform the Library’s acquisition practices. The format recommendations will help ensure the Library’s collections processes are considering and maximizing the long-term preservation potential of its large and varied collections.”
The recommended formats can be viewed here www.loc.gov/preservation/resources/rfs/ and cover six categories of creative output:
- Textual Works and Musical Compositions
- Still Image Works
- Audio Works
- Moving Image Works
- Software and Electronic Gaming and Learning
- Datasets/Databases
What I like about this recommendations is that they rank the various file formats on the digital side of things in order of preference. So even if you aren’t in the position to change your digital file’s format right now, you will know where it falls in the spectrum of long-term preservation.
For example, here are the recommendations for digital photograph files formats in the order of preference:
Formats, in order of preference
- TIFF (uncompressed)
- JPEG2000 (lossless (*.jp2)
- PNG (*.png)
- JPEG/JFIF (*.jpg)
- Digital Negative DNG (*.dng)
- JPEG2000 (lossy) (*.jp2)
- TIFF (compressed)
- BMP (*.bmp)
- GIF (*.gif)

FamilySearch and Ancestry: Billion Record Deal
Ancestry.com and FamilySearch International, the two largest online providers of genealogy data, just announced an agreement that’s expected to put a billion more historical records from around the world within reach online.
A billion is a LOT of records. If you wanted to count to a billion, it would take you 95 years.
According to an Ancestry.com press release, the organizations will partner “with the archive community over the next five years to digitize, index and publish these records from the FamilySearch vault.”
“The access to the global collection of records marks a major investment in international content as Ancestry.com continues to invest in expanding family history interest in its current markets and worldwide,” continues the release. “Ancestry.com expects to invest more than $60 million over the next five years in the project alongside thousands of hours of volunteer efforts facilitated by FamilySearch.”
This kind of collaboration (rather than competition) between these two enormous organizations will likely mean fabulous fruits for the genealogist. I love that the emphasis is on worldwide records, too. Though people in certain international markets may be the ones using their records, the ancestors of those folks have come from all parts of the world. As always, stay tuned to Genealogy Gems to hear news like this and for updates as these records start becoming available.
