HTTrack is a website mirroring utility that can swamp your disks with mirror copies of the internet. I’ve had to use it several times to make off-line copies of websites for all sorts of weird reasons. You’ll find HTTrack at: http://www.httrack.com. You can get a full list of command line options at: https://www.httrack.com/html/fcguide.html. There is a spiffy web and Windows wizard interface for HTTrack, but I gave that up.
This is the recipe for the command line options I’ve been using to produce a browse-able offline version of accreditation documents. This command says “Make an offline mirror of these URLs, go up to 8 links deep on these sites and 2 links deep on other domains. Stay on the TLD (.edu) and do it as quickly as possible. Be warned as it currently stands this will fill up about 1.5GB of disk space ;P.

The great part is that the archive grows as URLs are added.
