While hybrid Open Access began as an agreed method amongst publishers, scientists and libraries for a gradual transition towards full Open Access, it soon attracted various criticisms for being unfair.
Allegations of double dipping Since one source of funds to pay for open access articles is the library subscription budget, it has been proposed that there needs to be a decrease in the subscription cost to the library in order to avoid 'double dipping' where an article is paid for twice – once through subscription fees, and again through an APC. For example, the Open Access Authors Fund of the
University of Calgary Library (2009/09) requires that: "
To be eligible for funding in this [hybrid open access]
category, the publisher must plan to make (in the next subscription year) reductions to the institutional subscription prices based on the number of open-access articles in those journals." On 12 November 2009,
Nature Publishing Group issued a news release on how open access affected its subscription prices. However, university libraries were unconvinced that the decrease in prices was occurring. A report on work carried out by the University of Nottingham since 2006 to introduce and manage an institutional open access fund has been published by Stephen Pinfield in
Learned Publishing. In this article, the author comments that: ''"As publishers' income has increased from OA [open-access] fees in the hybrid model, there has been little or no let-up in journal subscription inflation, and only a small minority of publishers have yet committed to adjusting their subscription prices as they receive increasing levels of income from OA options."'' By 2018, this particular problem was considered so extreme in the area of open access book (as opposed to journal) publishing that the Anti Double Dipping Alliance was formed. == Institutional responses ==
