Dissertation Insanity

I am giving every article, chapter, and book I read for my dissertation a code based on what kind of literature it is. I am struggling to organize myself, whcih is hard because I have hard time organizing my half of the closet at home. Here is my current coding system.

Type of Paper:
T = Theory (PYD theory and any other theory that is included in this paper)
E = Empirical Research Study
R = Review
X = Not specified

Topic of Paper:
C = Civic Engagement in general
R = Religion (Effects of religion and spirituality on Adolescent Civic Engagement)
P = Parent (Effects of parents and family on Adolescent Civic Engagement)
M = Media (Effects of Media on Adolescent Civic Engagement)
X = Not specified

Design:
C = Cross-sectional / Time (Snapshots – correlations, associations, and differences)
L = Longitudinal / Time (Effects of Time on adolescent Civic Engagement)
E = Experimental design
X = Not specified

Number:
1, 2, 3.....N

Example:
ERL1 would refer to the 1st article that was and EMPIRICAL study on RELIGION which had a LONGITUDINAL design.

ERL2 would be the second of the same kind of article.

I am holding to some kind of belief that this will help me when I return to the notes I am taking and have a clue as to what I am looking at. Anyone else have a system for organizing loads of articles?
