RePEc collects a lot of metadata about publications in economics and finance, their authors, citations and more. All this data is provided by volunteers with the understanding that it is freely available for non-commercial uses while there is no explicit licence for the data.
By the very nature of RePEc, the data is highly decentralized and may be somewhat difficult to get to, at least for a novice. To this end, we have now a document that should help the potential user getting to it. It is not straightforward, and the data needs substantial massaging for the user to make good use of it. We hope this will be useful, though.
