Bookmarklet Links

Many search engines, like Google, offer a search bookmarklet. They work by performing a search on a piece of text you have selected on a page.

The most common type of bookmarklets link to functionality provided by a particular site. Bookmarklets of this type offer keyword search on WWW (search engines), keyword lookup (dictionary functionality), and HTML validation of your pages, among other things. We will probably see a lot more of these kinds of bookmarklets, as they offer a convenient shortcut to various WWW services which their owners are more than happy to promote.

Most of these bookmarklets function like this: Select some text on the page, then run the bookmarklet. The bookmarklet will contact a specific site which makes a service available. This service can be virtually anything - stock quotes lookup, articles search, dictionary lookup, translations, spell checking, address search on names, WWW domain name availabilty, price check on various shopping items, etc. etc.

Bookmarklet Collections

The kinds of bookmarklets mentioned above are found at sites which generally only supply one bookmarklet targeted at the specific service they offer. Not many sites offer a more versatile collection of ready-to-use bookmarklets (which is the reason I created my own site). But some do. I recommend these sites. - Lots of bookmarklets, though somewhat dated. Created by Steve Kangas, who is considered to be the inventor of bookmarklets.
