Scratchpads are an easy to use, social networking application that enable communities of researchers to manage, share and publish taxonomic data online. Sites are hosted at the Natural History Museum London, and offered free to any scientist that completes an online registration form. Scratchpad users include societies, journals, scientists, students and amateurs. Any group with an interest in natural history is eligible for a site and you do not have to have an academic affiliation, or any professional qualification. All you need is a little time, some information you would like to share, and a little experience using the web. You don't need to even be a member of a group, although the best sites are usually those developed by a community who make regular contributions.
