Want to know what these links do? Read on…

These five links represent a selection of 'social bookmarking' sites. Sites like these allow you to store, tag, and share links across the internet. Unlike your browser-based "favourites", social bookmarking allows you to share those links with friends, or access them from any computer you happen to be using. As a member of a social bookmarking site, you can save the link of any web page you come across, in order to create lists of useful or interesting internet resources. You can then share these lists with friends, people with similar interests, or the public as a whole.

When 'bookmarking' a page, it's good practice to add 'tags' or 'keywords' to describe the link, making it easier for others to search and find it. Some social bookmarking sites then rank pages in order, according to the number of people who have bookmarked them.

As you may have noticed, many BBC Radio pages now feature links to Del.icio.us, Digg,  Reddit, Facebook and StumbleUpon So how do you use them?

Well, firstly you'll need to register with at least one of the sites. Registration is free. It doesn't matter which you use, but each of the five sites listed has a slightly different set of features. Why not have a look around and take your pick? You'll find all the links below. Once you have registered, you can begin bookmarking.

If you come across a page on a BBC radio website (or any blog entry) which you find really interesting and want to save for future reference, just click the link at the foot of the page. When you bookmark a page, a link to it will be saved on your profile within your chosen social bookmarking site. You can bookmark any web page you like, inside or outside of bbc.co.uk.

If you want to find out more about social bookmarking, try Wikipedia or this article at BBC Collective.

Happy bookmarking!
