Please see the Explanatory Supplement for the most detailed technical information on 2MASS and the data releases. Other technical documents can likely be found here.
The DVD-ROM can be ordered using the order form.
The DVD-ROM is free of charge.
Here's a short list of DVD devices with which users have successfully read
both sides of the Release DVD-ROM:
The Release Catalogs, as well as the Release Scan Information Table, and

ftp site.
Yes, full-resolution JPG renditions of Atlas Images and Atlas Image mosaics
can be found on the 2MASS
Image Galleries.
Images in the 2MASS Image Galleries are in the public domain, so you are
free to use the images that you download from these sites. However, we ask
that you please use the following acknowledgement, where possible, with the

Given the sheer volume of Image data, the production of a DVD-ROM of this
sort is prohibitive. However, the full-resolution Atlas Images will soon

currently online via the IRSA Survey Visualizer.
The Explanatory Supplement is intended to be a "living document", i.e., it
is modified at frequent intervals, such that a hardcopy soon becomes outdated.
However, for future releases, we will offer the Supplement as a single
document on the DVD-ROM versions of the releases.
The Second Incremental Data Release is imminent!
To see what will be publicly available in the upcoming Second
Incremental Release (~47% of sky), please see the
Release preview page, specifically, the high-resolution preview tool.
