I’m currently sourcing journal articles on Social Capital, looking for links to learning, learning communities and social networks. Finding these either involves Google Scholar or Lancaster Universities meta-lib which is a web based search engine that collates results from a variety of online journals and the other ‘consolidation’ portals that are out there.
No matter where the journals come from they all end up in Papers, which is effectively iTunes for PDFs. It offers collections (which are like playlists), embedded notes and perhaps most importantly a match facility to get meta information (title, authors, dates, journals etc.) from a variety of online sources automagically. A fantastic piece of software which is a must buy for Mac users doing research.
