In May 2009 a European partner project BHL-Europe was founded by 28 consortium partners, mostly European libraries. Shortly thereafter another project BHL-China was launched in Beijing, in collaboration with the Chinese Academy of Sciences. Since then BHL in the strict sense has been called BHL-US/UK (usually only BHL-US), the global project has been referred to as BHL-Global, to distinguish it from the US/UK project. The global BHL project is managed primarily by the Smithsonian Institution (Washington, D.C.), Natural History Museum (London), and Missouri Botanical Garden. Six regional centers are planned.
