Everything Dulcimer - Closing Down.
Dulcimer Resources:TABS/Books/websites/DVDs
The Wayback Machine is a great resource, but because our site of interest (ie, EverythingDulcimer.com) still currently exists, there's a better option - use a website copier program to simply download the entire website to your hard drive.
Properly configured, programs like this will rebuild the entire website locally, with all of the tab, mp3s, midis, articles, etc. This takes a long time to do (as in hours in the case of EverythingDulcimer.com), depending on your internet speed and how "beefy" your computer is, but if you set it up and run it before you go to sleep, or before you head out to work, you may never notice. And it's a whole lot faster/more efficient than going through hundreds of tab files, articles, etc. to decide which ones you might like to keep and then downloading those individually.
I use HTTrack because it's free and has a pretty good interface (as far as these types of programs are concerned). But there are others that will also do the job, including WebWhacker, SiteSucker, SurfOffline, Grab-A-Site and more.
