Search Engine Cache
If you don't know about Google Cache or Yahoo Cache for that matter, then it's high time that you did. You surely must have noticed that "Cached" link right below most search result when you use Google or Yahoo to search for something. The thing is that Google and Yahoo have each sort of downloaded the entire internet to their data centre. Now because webpages are dynamic in the sense that they keep on changing, Google and Yahoo keep on uploading all the webpaged that they have downloaded, meaning they download a site every few days. Because they keep a copy of the sites, even if the actual site is down and out, you still access that stripped down version of the site using the 'Cached' button in Google and Yahoo's search result. It's that simple!
The Internet Archive
This is your library of webpages, so to speak. If you visit http://www.archive.org/, you'll notice that these guys store each website (sadly not the entire website, just important portion of it) and have archived mre than 150 billion pages. What does this mean for is? Greater access. A site might have gone bust year ago and these guys could still dig it up for you. Just log on to http://www.archive.org/ , type the URL of the webpage you want to go to, and click on 'Take Me Back' . If you want, check out http://www.kantipuronline.com/, the predecessor to ekantipur.com on the 'Way Back Machine'.
Web2Mail is an interesting little tool that lets you do cool stuff right through your email. You wouldn't even have to visit the actual page itself. All you have to do is send an email to firstname.lastname@example.org with the URL of the page you want to visit in your subject line. Within minutes, you'll receive a reply with the actual webpage, righ in you inbox! The best part is that you can even suscribe to any changes, meaning if the website of your liking is updated, you will be notified by email through Web2Mail.
