This paper reports on a renewed attempt to review and synthesise a substantial amount of research and development literature on Personal Learning Environments (PLEs) published in recent years. 

Earlier comprehensive review efforts (Buchem, Attwell, & Torres, 2011; Fiedler & Väljataga, 2011) had attested considerable conceptual differences within the research community. If and how these differences have qualitatively changed since 2010, is the focus of an ongoing literature review project. While the project is still work in progress, some provisional findings and insights are reported and discussed.
