OpSci: URIs, indexes and RSS for 72 closed-source publishers and scraper code.

I don't understand what this is... It doesn't scrape the full published articles/material on hidden/private URLs (unless you have access, paid for a subscription)? So what would one use this for?

It should be noted that this only <i>indexes</i> the journals and does not scrape the research PDFs themselves.

A very impressive achievement. Where can I find an example of how to use it?
