Want to have all your favourite web sites or articles bookmarked and available wherever you are, whatever computer you use? Try del.icio.us, Connotea or Citeulike
These are social bookmarking web sites and they all work in a similar way. Delicious has wide appeal across all interests, Connotea (owned by Nature) and Citeulike attract more scholarly users. They are "social" because many people use them to store and share interesting sites they have found. Your bookmarks are available to you whenever you're on the web because they are stored on a website, not just on a single computer.
After choosing one of these sites, register as a user and follow the simple instructions.
When you find articles or sites that you want to re-visit, bookmark them and allot a couple of tags or labels to enable you to find them quickly when needed. If you don't want to share your information, you can keep it private.
