I realize that there is a set of commonly recognized abbreviations used in the community this list is set up to serve. I would expect that KJV is pretty commonly understood as an abbreviation for King James Version. Having reviewed the question 1865 which has some pertinent answers to this question regarding proposed abbreviations for the names of the books of the Bible, and found myself on more than one occasion needing to research the meaning of an abbreviation used in a question or answer, would it be reasonable to suggest to users that the before an first time an abbreviation is used in a question or answer, it should be defined? As an example, a line such as
... in the New Revised Standard Version (NRSV) of the bible, ...
would precede in the question or answer,
... also in the NRSV, ...
although an exception might be made eliminating this need in an answer if the abbreviation is already defined in the question.
Or should there be a preferred list of accepted abbreviations (with definitions) added to the help facility so the most common abbreviations used on the list don't need this kind of treatment?
