# 17 Delicious and Diigo

Our Mathematics Department has preffered Social Book Marking Website Diigo over Delicious. My colleagues who previously had been using Delicious have also switched to Diigo. I have known about Delicious but haven't created an account with Delicious, instead I have signed up with Diigo and have been organising my bookmarks. You can also set up Groups in Diigo, e.g. Mathematics, and if you join the group, you can share your book marks with the group. I and some colleagues in our Mathematics group have added many useful sites in Mathematics group and we all are benefiting from the collection.
