A quick thread on how RePEc serves you on Bluesky:

1/ You can add your Bluesky handle in your author profile. It will then be listed on your IDEAS page and wherever your name appears on IDEAS.

IDEAS served 401 million page views in September 2025. We deem over 99.5% of that to be robotic. This shows the extend of the resources AI bots put on others.

When authors register with RePEc, they recognize which works they have written and build an online profile. A side effect is that this allows to distinguish (near) homonyms.

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.

Random paper from RePEc (@random-repec-paper.bsky.social)

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 ...

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.

Twice a year, we email people registered on the RePEc Author Service to alert them to possible works they could claim. We also delete any accounts with invalid addresses, as they serve no purpose.
