The Handbook of Research on E-Portfolios is the single source for comprehensive coverage of the major themes of e-portfolios, addressing all of the major issues, from concept to technology to implementation. It is the first reference publication to provide a complete investigation on a variety of e-portfolio uses through case studies and supporting technologies, and also explains the conceptual thinking behind current uses and potential uses not yet implemented. Over 70 international experts with countless years of experience lend this handbook the credibility that assures its readers of its extensive, recent, and reliable content. ""The Handbook of Research on E-Portfolios"" is the first handbook to investigate commercial and academic e-portfolio systems - home-grown, off the shelf, and open source - and to supply proof-of-concept evidence of successful systems.
