Great minds think (too much) alike

Check out this article in the July 17 issue of The Economist. It reports on a recent article in Science (18 July 2008: Vol. 321. no. 5887, pp. 395 - 399). Rather than leading to fuller citations, the growth of online databases of scientific journals has led to fewer articles being citied. The articles that are mentioned tend to be recent articles themselves. I recommend you take time to read the comments.
