BMC Research Notes publishes selected collections of research articles, conference proceedings, reviews and reports as supplements. While we build our new sites all supplements will be available here.

Aims and scope

BMC Research Notes is an open access journal publishing scientifically sound research across all fields of biology and medicine. The journal provides a home for short publications, case series, and incremental updates to previous work with the intention of reducing the loss suffered by the research community when such results remain unpublished.
