When I use layered citations, my first layer documents the physical item and my second layer documents the digital item. As I'm now usually able to generate compliant layered EE citations using my suite of custom templates, I see that I could easily incorporate a switch to suppress the digital layer during "publishing".
While I do not currently intend to "publish" in the commercial sense, I may provide copies to others. Those readers may wish to have only the minimum information on what was used as the basis of my research. They may actually find lengthy citations to be overwhelming.
If I were publishing commercially, an editor would no doubt severely trim the full citation to reduce costs. Retaining only the physical layer would seem to be one obvious starting point for generating a publishable citation through the editing process.
Can one legitimately remove the digital layer for "publication" purposes, while retaining the full citation in ones personal material?
