FADGI is the Federal Agencies Digitization Guidelines Initiative:
http://www.digitizationguidelines.gov/
The technical guideline has a number of sound suggestions:

(it also links dozens of English Wikipedia articles).
The verification software is available for free (only for Windows):

(Kakadu is not free software, sadly.)

Using Kakadu JPEG2000 Compression to Meet FADGI Standards
The Internet Archive is grateful to the folks at Kakadu Software for
contributing to Universal Access to Knowledge by providing the world’s
leading implementation of the JPEG2000 standard, used in the Archive’s
image processing systems.
Here at the Archive, we digitize over a thousand books a day. JPEG2000,
an image coding system that uses compression techniques based on wavelet
technology, is a preferred file format for storing these images
efficiently, while also providing advantages for presentation quality
and metadata richness. The Library of Congress has documented its
adoption of the JPEG2000 file format for a number of digitization
projects, including its text collections on
archive.org
<https://archive.org>.
Recently we started using their SDK to apply some color corrections to
the images coming from our cameras. This has helped us achieve FADGI
standards in our work with the Library of Congress.
Thank you, Kakadu, for helping make it possible for millions of books to
be digitized, stored, and made available with high quality on
archive.org <https://archive.org>!
