Embracing the principles of open access, the IEEE-SPS has partnered with Connexions, one of the world’s leading open education resource repositories, to develop and disseminate a critical mass of high-quality, peer-evaluated content and to make it available to anyone, anywhere, at any time, for free on the web as well as in a variety of other formats. Materials submitted to this project pass through a careful Society quality evaluation, ensuring that the content is deserving of the imprimatur of the IEEE brand for quality.
