Text in entry relates to "US+World Atlas" duo, so part about "and the U.S. Atlas contains" can be safely omissed, I think.
Also, I want to add that:
- "Full ISO Demo (@ The Internet Archive)" goes to v.3.
- Both remaining entries are about v4. So maybe it worth to add https://archive.org/details/The_Softwar ... scape_1993 that is World Atlas v5.
