Ars Technica reports that the House of Representatives have introduced a bill which could roll back open access in the name of copyright.
The House of Representatives has seen the introduction of legislation, HR 6845 that, depending on its final format, may significantly curtail or eliminate the NIH’s ability to continue its open access policy. The current bill would prevent any arm of the federal government from making research funding contingent upon “the transfer or license to or for a Federal agency of… any right provided under paragraph (1) or (2) of section 106 in an extrinsic work, to the extent that, solely for purposes of this subsection, such right involves the availability to the public of that work.” Those Section 106 rights include the reproduction of the work.
Although that would seem to rule out the existing NIH policy, there is a certain amount of legal wiggle room there. For example, the NIH could fund a private entity to maintain PMC, and thus have the right to reproduction transferred to an independent entity. Nevertheless, the bill would appear to directly target the prior legislation that put the NIH in the business of mandating public access in the first place.
If you want the public to fund your research, then the public should have free (libre) access to your publications. If profit is your motive, you can fund the research yourself.
