First we had “open access” in which people can download, read, reuse and redistribute content. Then we had “public access” in which people can download and read content. Now we have “free access” in which people can read for free in a proprietary browser, and can’t download or print.
Is the new Nature policy, which allows authorized readers to create links to heavily-DRMed but full-text copies of articles, a step forward in access to knowledge? I’m skeptical. With so many restrictions, it makes the informal exchange of PDF copies look like an enviable system.
