A true international effort, this extensive directory of over 3,700 briefly annotated botany-related Internet resources is coordinated by individuals in the US, Canada, and Finland. The Subject Category list is maintained by Raino Lampinen of the Botanical Museum of the Finnish Museum of Natural History. Sites included in the directory have been categorized into at least one of 18 areas, including arboreta, botanical societies, taxonomic databases, images, ethnobotany, paleobotany, and more. The What's New section is updated every two or three weeks and includes both new and newly-discovered resources as well as notes on URL changes to previously listed sites. Users can register for a URL minder service for the Subject Category List to automatically receive email messages whenever updates are made. From the IBD home page users can browse lists of resources arranged alphabetically. Multiple mirror sites are available.
