Sites such as Google Scholar, Web of Knowledge and PubMed cover a vast number of journals. This makes these sites massively powerful and influential even though they cannot cover all the relevant literature. The report also tackles the question of why only few researchers use advanced searching. (Perhaps they are too easily satisfied?).
It is well worth looking at the one page summaries of the 1st and 2nd phases. See pages 4 and 9 of the report by the UK Research Information Network, click on E-journals: their use, value and impact and scroll down to the Phase 2 report (in red)
We would love to know what you think are the implications for African researchers – both as searchers and writers of papers? And what if anything should librarians do about it?
