Sample figure title. Distribution of the publications from the BI journal corpus and from the MI journal corpus over time. The number of publications continuously increased BI domain a continuous increase in publications in the used journals took place. In the MI field the number of publications fluctuated over time, which might be the result of conferences that did not take place every year. Relative low publication figures in 2005 are partly due to the fact that not all publications of 2005 have yet been incorporated into the Medline distribution. Nevertheless, the publication number in 2005 in the BI field showed already an increase in published articles, which could be the result of open access publishing.
