Last year, the KB presented the initial OPENBIB data release, which contains selected and curated metadata from OpenAlex. See this new blog post tinyurl.com/58zmb79z for an updated data release based on the OAL snapshot from July 25. This data release also features a KB author disambiguation system.

This is a new preprint on the impact of the COVID-19 pandemic on international researcher mobility.
The analysis estimates approximately 14,700 fewer international researcher movements between 2020 and 2022 than expected, corresponding to a global loss of about 3.7%.

If someone paid you $4.75 every night you slept 7+ hours, would you sleep more?
And--more importantly--would that increase in sleep change your behavior in other meaningful ways?
