Social Bookmarking

Social Bookmarking is when someone annotates a book online. for example if someone is to annotate a book for school online and they create citations and they cite evidence and talk about the book and its quotes, that is an example of Social Bookmarking. The purpose of Social Bookmarking is to be able to understand text better and to give better insight on something. I would suggest Social Bookmarking for others because it is useful and can help people when they are trying to cite someone or a such text.
