SPARC has released Income Models for Open Access: An Overview of Current Practice.
Here's an excerpt from the press release:
"Who pays for Open Access?" is a key question faced by publishers, authors, and libraries as awareness and interest in free, immediate, online access to scholarly research increases. SPARC (the Scholarly Publishing and Academic Resources Coalition) examines the issue of sustainability for current and prospective open-access publishers in a timely new guide, "Income models for Open Access: An overview of current practice," by Raym Crow.
"Income models for Open Access: An overview of current practice" examines the use of supply-side revenue streams (such as article processing fees, advertising) and demand-side models (including versioning, use-triggered fees). The guide provides an overview of income models currently in use to support open-access journals, including a description of each model along with examples of journals currently employing it. . . .
Developing a sound business model is a critical concern for all publishers and the process can be especially challenging for those considering open-access distribution. The guide recognizes that the needs of individual journals differ, and that publishers will apply a variety of income models to support open-access distribution. The right model must take into account not only the publisher's need to cover expenses, but also the organization's mission objectives, size, business management resources, and other factors. . . .
"Income models for Open Access: An overview of current practice" is available for free to read or download online. The guide is supplemented by an extensive Web resource, which invites community discussion on models described as well as contributions related to new and other models.
