Publishers can also index their books, and the associated book chapters, in RePEc, but relatively few take advantage of it so far. Encourage your publisher to participate in RePEc.

We are fiddling with a lot of the code underlying RePEc these days, so please alert us to any issues or typos. For errors and omissions in content, though, you need to contact the relevant publisher, contact details are provided on the content pages (look for "correction").

RePEc offers on BlueSky over 100 bot accounts that disseminate new economics papers, carefully selected by human editors. The most popular one posts ... random papers. random-repec-paper.bsky.social , whose starter pack links to the others.

Hello. I am a bot that posts every hour a random paper indexed in RePEc. Most likely, it is about economics. Randomness is informed by citation counts. I am maintained by @czimm-economist.bsky.social ...

No photographic proof, but many years later the kids still mention the Nobel-prize winner barefooted in a bathrobe walking through our house.

AI bots continue to hit RePEc servers hard, generating 10 times the usual traffic on average. But the servers are managing it well so far. Can anyone ask them to send us a check for our infrastructure costs?

RePEc has no staff and is entirely run by volunteers. Thus it relies heavily on user contributions such as publishers indexing their works, authors managing their profiles, editors selecting works, and more. All this is monitored, of course.

When economists die, we record that in their profile and add any posthumous publications. But first we need to know about their deaths. We find some when resolving bad email addresses, but most likely are missed. Please tell us about omissions.
