Databib is a searchable registry of research data repositories. It can help you identify and locate online repositories that could be suitable hosts for your research data; it can also help you identify and locate research datasets that may be useful in your own research and teaching.
Data records are annotated, containing standard information fields – descriptive metadata, if you like – making it easy to search and browse across broad disciplinary categories (e.g. Geosciences). The Databib record describing the Paleobiology Database, for instance, looks like this and provides brief information about the authority maintaining the database, the terms of access, deposit, and reuse, and the type of data accepted.
It’s a work in progress, built by community, overseen by an editorial board, and hosted at the Purdue University Libraries (recognized leaders in the domain of data curation and management.) I did notice a somewhat startling range of repository types; for instance, the Geological Society of America’s supplementary data site is listed, – it IS a data repository, I suppose, in that it hosts supplementary data for articles published in its journals, – but still a very different use of the word ‘repository’ from, say, the National Snow and Ice Data Center (NSIDC) (accepting data submissions from registered investigators /researchers) or one of the World Data Centres.
Take a look and see what you think. It’s a great start, with 519 data repositories registered to date. Not perfect, but then neither were a lot of community-built projects when they got started (SourceForge, Wikipedia … )
