Everyone knows the pain of finding an interesting article and then realising that you don't have access to it. It's not fair. If you work for a university there is a good chance that your library does subscribe to the journal but figuring out how to access it will take a few steps. But now if you work in Cardiff University, at least, Google Scholar just got a lot more interesting. It is now easy to know which journals you really will have access to.
This made me think... wouldn't it be great if Google Reader knew which journals I have access to? And is there a search engine which accesses PubMed which knows these journals? If you know the answer to this, let me know!
