The disciplines of Personal Information Management (PIM) and Personal Knowledge Management (PKM) both have to do with the capture, collection, and curation of information. The main difference between the two disciplines seems to be in the output.
For a graduate research paper where source material is captured and used as a factual basis to support an argument, the process of PIM fits the bill.
PKM on the other hand, is more about the practical application of information, sometimes in new and novel ways. As such there are aspects of sensemaking and social collaboration involved in PKM than may not be required in PIM.

My blog post on the subject: Personal Knowledge Management – is it PKM or is it PIM?
PKM originated with the practice of knowledge management, which began when researchers needed to keep track of information on personal computers SEE note on Origin of Personal Knowledge Management
For a broad overview of PKM see note on Personal Knowledge Management
