RePEc sites have served over 600 million abstract views (TBH, the last couple millions came from AI tools, and we are not sure they were triggered by humans)

On the other hand, some people come out only once in their lifetime.

The problem got worse, now thrice the expected abstract views instead of twice. Further vetting is not going to move the needle much. I am considering dropping that as a ranking criterion.

RePEc lives from volunteers. A good example is EDIRC, the directory of economics institutions has captured the names of its contributors:

Most temporary licence plates are expired in St Louis, some for several years. The reason is that you need to pay sales tax to get the real plates, and local police does not enforce. This is going to change in a year in Missouri when car sellers also collect the tax at the sale.

Today in the US it is the day of Thanksgiving. This is the opportunity to thank all the volunteers who help index publications in RePEc, edit NEP reports, send corrections to EDIRC, amend Genealogy records, or edit Biblio topics. RePEc would not exist without them.

RePEc is run by volunteers, thus we rely a lot on self-help: publishers push their metadata, authors maintain their profiles, users can contact publishers about errors and omissions, etc. Do not hesitate to be proactive!

Bots are back with a vengeance, hitting IDEAS at a record rate. Sunday saw as many page hits as for a half year of usual robot filtered traffic.This is going to make the November statistics even more problematic than October. The server is mostly holding up though.

Why are there two RePEc sites offering similar services? Because we believe in healthy competition and want to offer users choices! And do not worry, we do collaborate.

RePEc does not add research works automatically to an author's profile because there are too many people with similar names. Thus, do check your account from time to time, something may be waiting for your action!

Given the constant struggles with AI bots hitting my server, I considered using Cloudflare. But the cost is high, and it adds another possible point of failure. I guess I was right.

Some RePEc archives go silent when their maintainers move on, and contents do not get updated. If your local archive is in that position, here are instructions on how to get yours back on track.
