Sharing information and building on the findings and experience of previous work is central to most scientific activity. The Internet is now a powerful and almost limitless medium to do this efficiently. The example used is the National Biodiversity Network?s Gateway (www.searchnbn.net) through which data on the distribution of native and introduced species of freshwater crayfish in the UK are now accessible via the Internet. The NBN Gateway enables data owners and custodians to provide controlled access to their data for other users. Users are able to examine species data in relation to other spatially referenced datasets, such as the boundaries of designated and protected sites, and to link to other sources of information.
