I am working on a Masters Degree thesis. I am interested in books or journal articles where recent knowledge management literature has been analysed/grouped/classified. Questions that come to mind are  (1) what VARIABLES were used to classify literary works?  What methodology was used to identify the articles (3) Are there any visible categories knowledge management literature. (4) Is there a blue print/tool that can be used to study  several KM articles, understand them and then build a taxonomic map?
