Last Thursday my colleague Julie Graves Krishnaswami and I walked into The Harvard Bookstore and after an hour of downloading the file watched a copy of the Yale Law School faculty publication Before Roe v. Wade: Voices that Shaped the Abortion Debate before the Supreme Court's Ruling get printed in about 10 minutes. A video of the book getting printed is below.
The Yale Law Library has worked with Linda Greenhouse and Reva Siegel to publish the 2nd edition of this book, and to make it as widely available as possible. It is available online and in print.
The book is available for free online as a PDF, and an ebook (epub/mobi), and in Google Books. It is also available as a print on demand book from Amazon and Barnes & Noble.
Finally the books is also available as print on demand anywhere you can find an Espresso Book Machine where you can print your own copy.
