Unsurprisingly, many of the articles were evaluations of types of software running on Linux systems. These included tools for recording rat activity levels, data management, statistical analysis and 3D image browsing. Many were to do with various kinds of DNA analysis, and biological topics predominated, largely because of the dominating presence of the BMC Bioinformatics articles. Several articles referred to 'Linux clusters' -- groups of interdependent Linux computers running large data-processing applications -- and how to improve their performance. A third group looked at networking technology and one article (in Spanish) took on the social impact of technology: 'Hackers: de piratas a defensores del software libre'.
Searches for the names of the best-known Linux distributions found nothing, with the exception of 'Fedora', which turned up four hits. ('Gentoo' turned up one hit but this proved to be an article about penguin research! ) A search for 'Microsoft Windows' tuned up 13 documents. Searching for 'open source' retrieved 261 documents.
