Has anyone heard of the "Central Library of Medicine Foundation"?

After googling for the Central Library of Medicine Foundation, I found the following post on the University of Muenster site (note I used Google Translate to translate the piece from German to English):

Recently, faculty members have received many article requests from a "Central Library of Medicine Foundation", which was apparently acting on behalf of South American doctors.

While researchers are usually happy to accommodate private, direct inquiries from colleagues, there is naturally some skepticism, since we do not know if this service costs the requesting physician or how much the "Central Library of Medicine Foundation" receives.

After some inquiries with South American and Spanish-speaking colleagues the following picture emerges: the website www.rima.org (The "Central Library of Medicine Foundation" aka "Fundación Biblioteca Central de Medicina" aka "Red Informática de Medicina Avanzada" (RIMA)) is a non-library organization based in Buenos Aires that offers physicians and researchers to get an article for a given fee (the exact amount is unknown). RIMA neither buys the article from the publisher nor copies it from a local library (which presumably cannot afford journals), but services the requests by directly forwarding them to the authors, in many cases, Münster faculty members. This probably the name "Central Library of Medicine Foundation" is used to simulate the unselfish non-profit library.

Everyone must of course know how to handle it themselves. To send a reprint by email costs only a push of a button and it helps indeed ultimately a colleague who is certainly not as well supplied with magazines as oneself. On the other hand, you will be benefiting a commercial (?) intermediary organization, which may not help you, either. But maybe it is just a clever business idea of 10 unemployed Argentine doctors, to help them earn a living. . . .

So it seems that this Central Library of Medicine Foundation is a business that charges a fee to its clients for obtaining a paper, via you. Although this is probably not really legal or moral, this fee is probably lower than what, say, Elsevier is asking for the same paper. I think this situation makes a good argument for open-access journals.

Received a similar solicitation from the same person. She says she is in Argentina, the country code to her phone number is for Spain, and the webpage is a Moldova domain.

This all seems a bit dodgy.

I'd prefer to help colleagues out as much as possible...I certainly have no problem sending a PDF to an individual upon request. But this seems to be a (possibly for-profit) enterprise and I'm certain it would violate the copyright of the publisher.

I just received a similar request, but this time it was from a person named "Silvia Alderico" at the same institution as above. This whole enterprise does not seem legitimate. Normally, a researcher contacts you directly and asks for the paper, or their institution pays for the paper directly. If you have a desire to fill the request legally, most journals allow you to post a version of your paper: usually the final version you submitted to the journal that was accepted for publication (double-spaced word document or PDF, with figures and tables at the end).
