This wiki-based home page has been my main home page since June 2013. If I move to another page, I'll say so here and link to the new page.

My work and primary affiliations

  • My primary field is philosophy (Ph.D., Northwestern University, 1978). I'm also a non-practicing lawyer (J.D., Northwestern, 1982).



My latest book is Knowledge Unbound (MIT Press, 2016). It's available in paperback, hardback, and many open-access editions (same text, different file formats).


My last book before that is Open Access (MIT Press, 2012). It's available in paperback and many open-access editions (same text, different file formats). I keep it alive with frequent updates and supplements. Choice named Open Access an Outstanding Academic Title for 2013.
  • Nearly all my publications are open access from my section of DASH (the Harvard open-access repository), my Earlham web site, a publisher's site, or some combination of these.
    • One kind of exception is an older, print-only publication for which I don't yet have a digital edition. Over the years I've gradually created digital editions where I didn't have them, and I'm nearly done.
    • Another kind of exception is a work for which I have a digital edition but not permission for open access. The only exception of this kind is The Case of the Speluncean Explorers: Nine New Opinions (Routledge, 1998). I published it before I started thinking hard about OA. I've asked Routledge to make the book OA, but it declined. I'm still willing to do so as soon as Routledge is. If Routledge doesn't make it OA while the book is still in print, then I'll make it OA as soon is it goes out of print and the rights revert to me.


  • When I was a philosophy prof (c. 1982-2003), I specialized in Kant and German idealism; the history of modern European philosophy, roughly from Montaigne to Nietzsche; the history of western skepticism from Socrates to the 20th century; epistemological and ethical issues related to skepticism, such as fictionalism, ideology, self-deception, and the ethics of belief; the logical, epistemological, ethical, and legal problems of self-reference; the metatheory of first-order logic; the ethics of paternalism, consent, and coercion; and the philosophy of law. I retain an interest in all these topics, and have since added some new ones: the connections between ancient Greek skepticism and Buddhism (via Pyrrho), the naturalization of ethics, and concepts of randomness.
  • In my post-prof life, my interests center on policies, practices, and technologies that foster knowledge, especially those that foster the growth, sharing, integration, use, and usefulness of knowledge. In addition to promoting these policies, practices, and technologies, I want to understand how the internet has changed research, scholarship, and education, how it ought to change them, and what it would mean to take full advantage of the internet for these purposes.

Other current affiliations

Background and past affiliations

  • In May 2003 I gave up my position as a tenured, full professor of philosophy at Earlham College, where I had taught since 1982. I also taught computer science and law. I left my professorship in order to work full-time on open access to research, which I've done ever since. However, I'm still a research professor at Earlham and still work full-time in the academic universe.

  • Archived sites and pages
    • Harvard's H-Sites preserves three of my web sites:
    • Most of my old blog, Open Access News (2002-2010), is backed up and searchable in a Google Group of the same name. I forget what trick I used to send each blog post to the Google Group. But whatever it was, I didn't think of it until after I'd been posting for a while. The Group captures about 14k of the 18k posts. You don't need to be a member to view or search the Group.
      • All the posts should be captured in the first of the H-Sites back-ups above, although that copy is harder to search.
      • The Google Group search is better but still leaves a lot to be desired. If you search for "Elsevier", it will tell you there are 11 hits. But if you scroll through the hit list to the end, you'll find 203. If you scroll back to the top, you'll see that Google updated its estimate to 203.
      • You can also search the blog in Google. Just precede each search string with "peter suber" and "open access news" (keeping the quotation marks). This method will include some hits that quote my blog posts, but it won't omit any of my blog posts.
      • You can also search the blog with a Google "site" search the section of my Earlham site containing the blog.

Social media

  • I tweet as @petersuber and blog at Google+ as +petersuber.
    • I have accounts on Diaspora, LinkedIn, Mastodon, and other social-media platforms, but don't use them. I deleted my Facebook account for reasons like those laid out in this 2010 article.
    • Although I'm picky about social-media sites, that doesn't mean that the two I use have my unqualified endorsements. On the contrary, Twitter and Google+ are both deteriorating, and the niche for something better grows larger all the time.
    • If you have a serious question for me, please consider a channel that gives me space for a serious answer, like email or Google+, not Twitter.
  • Nowadays I post little to social media. But from 2002 from 2010 I blogged intensively at Open Access News — about 18,000 posts over 8 years, with occasional blogging partners. OAN was my attempt to stay on top of all that was happening with OA and share what I learned. It was useful while it lasted, but it didn't scale with the growth of OA. That failure to scale led me to launch the crowd-sourced and tag-based Open Access Tracking Project in 2009, and lay down my blog about a year later. I explained why I was making the transition in a May 2009 article in my newsletter. The blog archive remains online for searching, with another copy preserved in a section of Harvard's H-Sites.

  • My primary email addresses are and
    • I also use <>.
    • I no longer use <> or <>. If you have them in your address book, please replace them with one of the above.
  • Email is the best way to reach me. If you want to contact me by phone, fax, snail mail, or some other way, and don't want to go through the Office for Scholarly Communication, then send me an email and I'll tell you how. If you send me a message by social media, I probably won't see it.
