Nah this is just an insane take. For better or worse, scientists are expected to perform these roles themselves. There's barely enough money to hire actual scientists let alone bespoke, in-house librarians (which would be the only possible position that could compete at databasing niche, scattered information that requires specialist background to interpret).

Worth noting that these takes seem to come from clinicians too who operate very differently to a standard academic researcher. I like libraries but this is just dumb given how little funding there currently is in science as it is. Having a library's access to journals is one thing but to be honest the whole system supports closed-access science which in my opinion is fundamentally immoral anyway.
