[RePEc-announce] RePEc in December 2025, and a look back at 2025

[Christian Zimmermann]

RePEc services continue to see increases in traffic that we find hard to
believe, with 371,613 file downloads and 6,441,286 abstract views in
December 2025. But more on that below. We welcomed a few new RePEc archives
over that month: Lutsk National Technical University, International
Emerging Scholars Society (IESS), EconSciences Library, University of Linz
(II).

Now regarding last year as a whole. Two points marked the year: First, many
of our sites are getting rewritten from scratch, an initiative that is
going to be completed in a few months. Second, we have struggled with AI
bots, initially when they overwhelmed our servers with requests as they
were trying to collect our information, and then they started generating
traffic that became difficult to distinguish from human traffic, which
messes with our statistics. More details are provided in a recently
updated, separate blog post
<https://blog.repec.org/2025/11/10/ai-issues-in-repec/>.

Of course, RePEc continues to grow, thanks to 48 new RePEc archives and our
existing publication contributors, over 2000 of them. Some highlights: 220
new working paper series, 70,000 new working papers, 260 new journals,
260,000 new journal articles, 56,000 new book chapters, 7,000 new books,
200 new software components, and 2,600 new registered authors, with all
authors adding 108,000 works to their profiles. References were extracted
from 175,000 new documents, 4,200 NEP reports were issued, and users made
19,000 amendments to the RePEc Genealogy. Finally, 29,000,000 abstracts
were viewed on the reporting websites, who facilitated 4,200,000 document
downloads.

For 2026, we expect to conclude the code rewrite and then start again with
introducing new features. We will for sure have to deal with artificial
intelligence, at least as much as last year, mostly as a nuisance. And we
look forward to continue serving the economics profession with free
services.
