Pick your own: Literature reviewing tools

I've just written article for Information Today Europe on five tools for helping you carry out a literature review and manage the multitude of references academics and students now have to juggle. Gone are the days of working in a single location, hunting down papers from journals and scribbling notes on to cigarette packets when you came across something useful.
These days students are more likely to source Tweets, videos, grey literature and Wikipedia amongst many other resources, how you save these useful bits of knowledge has become an increasing challenge; so hopefully the article and tools mention will go some way to streamlining your literature review process.
