Our analysis indicates that several specimens of dubious origin collected by Charles Craven are likely to have originated in Amazonia, not in the northeastern Brazilian state of Pernambuco as stated on their original labels with implications for our understanding of historical extinctions 9/10
Our findings justify doubts on the geographical origin of many other Craven specimens allegedly collected in Pernambuco raised by other ornithologists (Salvadori 1891, Naumburg 1939). These biogeographically unlikely specimens are mostly species otherwise only known from Amazonia, but also including some species otherwise only known from northern (e.g. Baudo Guan Penelope ortoni, USNM 107214) or southern (e.g. White-throated Hummingbird Leucochloris albicollis, USNM 107185) South America. These specimens may have been collected in other regions and mislabelled as originating from Pernambuco, perhaps after being shipped from Recife to foreign collections. Additionally, Craven may have been the dealer rather than the collector of these specimens, which may have been obtained by third parties in multiple different locations across South America and subsequently sent to Craven in Pernambuco. Our results suggest that all these specimens should be assigned uncertain provenance, and the species must be removed from lists of historically occurring species in northeastern Brazil. Stable isotope analysis offers a promising tool for verifying the origins of specimens with uncertain locality data, enhancing their scientific value, and resolving biogeographical and evolutionary questions.

It is not "attribution and sourcing" to generate post-hoc citations that have not been read and did not inform the student's writing. Those should be regarded as fraudulent: artifacts testifying to human actions and thought that did not occur.

For help with attribution and sourcing, Grammarly is releasing a citation finder agent that automatically generates correctly formatted citations backing up claims in a piece of writing, and an expert review agent that provides personalized, topic-specific feedback.

What the shit, Clarivate! Anyone using Ebook Central MARC records, be warned. They're jamming those records with AI generated metadata. Auto-enabled but you can disable it.
Dear Alex,
We are writing to share an important update coming to Ebook Central that will help improve ebook discoverability. At the end of October 2025, Ebook Central Express MARC records will include AI-generated metadata when publisher metadata fields are not available.

Why are we introducing AI-generated metadata to Ebook Central records?

Most publishers include subject information in their metadata, but there are times when this information is not included, leading to limited search availability in discovery systems. For this reason, we are providing AI-generated Library of Congress subject headings only when not available from the publisher to improve the completeness of our metadata and discoverability of Ebook Central titles.   Which AI-generated fields are included in Express MARC? 

The AI-generated fields will include Library of Congress Subject Heading (LCSH) (6XX); Library of Congress Classification (050); Dewey Decimal (082); Description (520); and Source of Description (588). To learn more, please visit our FAQ page.

I have been trying to explain a microfiche machine to one of my dear, brilliant, talented, but clearly too young to be alive collaborators. And it is taking the last of my soul.

“Micro…fish?? I have never heard that word in my life.” I recorded the timestamp so it can be put on my tombstone.

The elimination of exact text search from a growing number of services is a form of enshittification that I keep getting surprised by. It's search: computationally expensive (?) and a foundationally useful tool. Blunting it into uselessness is a shocking capitulation to the internet as garbage pile
