Traditionally, academic researchers have been using platforms such as conferences, academic journals and books to present their findings and engage in academic discourse with their peers. The development of Information and Communication Technologies provides researchers not only with new tools, but also with new means of interaction. Among the new platforms are also weblogs (blogs). Formerly defined as `online logbooks', blogs can be used for a variety of purposes. A small but growing number of researchers write research related blogs. In this paper we present a qualitative, explorative study, carried out with the aim of describing and structuring information provided by academic researchers in their blogs. We describe a framework for categorising blogs and blog posts as well as patterns of blogging behaviour we have observed in research blogs.
