My reference scheme

I use my own reference scheme to describe Arg3551. This reference scheme enables me to have a more complete listing of the issues. I consider it a temporary scheme until I am able to arrive at a fairly complete listing.

The scheme combines:
1. The donomination in a computer-friendly format: For example, instead of 1/2c I use 05c, and instead of 2 1/2 c, I use 2p5c.
2. Mention of the person on the stamp (optional) or name acronym: I need this naming convention for the 3 centavos stamp, which was issued with the San Martin (SM) and Mariano Moreno (M) designs. The 20c Martin Guemes was issued with (JMG) or without (MG) the middle name shown.
3. Reference to the paper if I know of more than one: There are 30c1E1, 30c1E2, etc. If the stamp was only issued on one paper, there is no need for this naming convention, as is the case for the 3cSMGr, which was only issued on the 1E1 paper.
4. An additional reference for a specific plate: This naming convention is required for the 10c Rivadavia red, with types I and II, and the 10c Rivadavia Brown, with types A and B.
5. An additional reference for a scpecific color: This naming conventions is required for the 15c Small Format Cattle, issued in dark blue and only on the 1E1 paper, as 15cSC-D, and also issued in light blue and on a later paper, as 15cSC-L.

I mention several examples that show how my naming convention works:
1. The 8c was issued on one design, on one paper, on one plate, and on one color. Reference: 8c.
2. The 10c Rivadavia was issued in red and a range of browns, on many papers, and on at least four plates. Example references: 10cR-I, 10cBRCL1-A.

For the 18 papers I use the following scheme:
1. The early papers with the first watermark are the 1Ex papers, with x as of this edition being 1 to 4.
2. The clay papers were printed in two groups, CL1A and CL1B in 1943; and CL2A and CL2B in the 1950s.
3. The unwatermarked papers are of two types: grid from 1945 (NGR), and opaque from approximately 1948 (NOP).
4. The paper with the second watermark is found in three types: clear (2C), diffuse (2D), and with narrow rays (2N).
5. The late papers with the first watermark are the 1Lx papers, with x as of this edition being 1 to 5.
