Readcube is a desktop tool (available for Mac and Windows) that aims to help students and teachers search and organize their research more effectively. I wrote this review of Readcube last month. This week Readcube launched Readcube Boot Camp to help users use Readcube better. Right now the Boot Camp has four video tutorials offering tips for searching, annotating, and organizing.
Applications for Education
Readcube is targeted toward university use, but it could also be helpful for high school students working on long term research projects.
