Chris Biemesderfer has self-archived "Fully Digital: Policy and Process Implications for the AAS" in arXiv.org.
Here's an excerpt:
In the near term, we anticipate that enterprise-scale printing will be phased out in the next 2-3 years, as the library subscribers to the journals stop acquiring the print products. We are going to be looking to web-to-print solutions so that customized print products can be specified by the customers themselves, thus allowing the AAS to focus on the larger issues of professional scholarly communication. In the meantime, we are thinking about a business model for the Society that offers only online subscriptions, and we are preparing to charge authors in 2011 based on the quantities of digital material that are submitted, rather than based on the number of typeset pages of the authors' text.
