During the 1974–2004 period, the sleep literature had quadrupled (2384 publications in 1974, and 9721 in 2004) while overall
scientific productivity had only doubled. The set of the seven most productive countries (USA, Japan, United Kingdom, Germany,
France, Canada and Italy) in sleep research, and the geographical region distribution remained stable over the three decades.
On the other hand several indicators appeared in the sleep research literature during the 1990s: the increasing productivity
of sleep researchers; the growing number of countries publishing on sleep; the continuous creation of sleep-focused journals;
the scattering of sleep publication among increasingly more scientific journals; the turnover among the leading journals;
and the emergence of new entities such as China, Turkey, and the European Union.
This study analyzed 2443 papers published in 2006 by European Union authors on pain-related research. Five EU countries (the
UK, Germany, Italy, the Netherlands and France) each published > 200 papers while three countries (Cyprus, Malta and Estonia)
published none; socio-economic indicators were related to each country’s productivity. The 2443 papers were published in 592
journals and Cephalalgia, Pain and European Journal of Pain were the most prolific. Publications were also analyzed for intra- versus inter-EU/non-EU collaborations and subdisciplines
profiles in Clinical Medicine and the Life Sciences for the World, USA, EU and the top-four EU countries were compared.

bibliometric analysis of the literature covering a one-year period (2003) was
performed to evaluate the number of scientific publications on sleep and its
distribution among the European Union countries. 912 articles appearing in Life
Sciences and Clinical Medicine journals indexed in the Institute for Scientific
Information databases were downloaded. These articles were authored by EU
researchers; Germany, the United Kingdom, France, and Italy rank at the top of
the EU countries. The output distribution of the most productive EU countries
are also presented and discussed. Despite the limitations of the methods used,
the present results give an interesting snapshot of the EU publishing behavior
in sleep research.
