The distribution database (DDb) is maintained by the Botanical Society of Britain and Ireland, to store and make accessible the ever-growing pool of biological records collected or collated by the society. 

The DDb, which holds over 50 million records, provides vice-county recorders, research workers, Agencies and NGOs with on-line access to large, detailed data sets and, where appropriate, allows data to be edited to correct mistakes or to add annotations. 

The DDb provides access for everyone to distribution maps and a range of tools for checking and formatting records.
