Journal of the History of Ideas

Since its inception in 1940, the Journal of the History of Ideas has served as a medium for the publication of research in intellectual history that is of common interest to scholars and students in a wide range of fields. It is committed to encouraging diversity in regional coverage, chronological range, and methodological approaches. JHI defines intellectual history expansively and ecumenically, including the histories of philosophy, of literature and the arts, of the natural and social sciences, of religion, and of political thought. It also encourages scholarship at the intersections of cultural and intellectual history — for example, the history of the book and of visual culture.

Open Library

Our goal is to provide a page on the web for every book ever published. At its heart, Open Library is a catalog. The project began in November 2007 and has been inhaling catalog records from some of the biggest libraries in the world ever since. We have well over 20 million edition records online, provide access to 1.7 million scanned versions of books, and link to external sources like WorldCat and Amazon when we can. The secondary goal is to get you as close to the actual document you’re looking for as we can, whether that is a scanned version courtesy of the Internet Archive, or a link to Powell’s where you can purchase your own copy.


Open Logic Project

The Open Logic Project is a collection of teaching materials on mathematical logic aimed at a non-mathematical audience, intended for use in advanced logic courses as taught in many philosophy departments. It is open-source: you can download the LaTeX code. It is open: you’re free to change it whichever way you like, and share your changes. It is collaborative: a team of people is working on it, using the GitHub platform, and we welcome contributions and feedback. And it is written with configurability in mind.
