Free Public Access to PPMI Publications

The intent of the PPMI publication policy is to provide for open, free, public access to analyses of PPMI data. Publications authored by the Steering Committee or by PPMI investigators using PPMI data shall be published in an open-access journal or in a hybrid open-access journal as a fully open access article, and/or posted to an open-access repository under the Creative Commons Attribution 4.0 Generic License (CC BY 4.0) or an equivalent license. BioRxiv (“Bio-Archive”: http://www.biorxiv.org/) is the preferred repository for PPMI publications. Publication under other, more restrictive licenses (e.g. CC-BY-SA) may be considered on a case-by-case basis. Under extraordinary circumstances, authors may request an exception to this policy by applying to the PPMI Executive Steering Committee. Authors may submit requests to PPMI’s sponsor, MJFF, to cover the fees required by a publisher to effect publication on the aforementioned terms. Requests for cost coverage of publication fees must be made prior to the author paying fees to the publisher. Requests for retroactive reimbursement for open access fees may be considered by MJFF on a case-by-case basis. External users of PPMI data are strongly encouraged to publish results in open-access journals or in a hybrid open-access journal as a fully open access article, and/or post to open repositories.
