For honor, glory & union : the Mexican and Civil War letters of Brig. Gen. William Haines Lytle / Ruth C. Carter, editor. (OCLC #897380031)

I often hear the generalization “don’t use abbreviations in RDA”, but this mainly refers to non-transcribed elements which under AACR2 would have had abbreviations, like “39 p.” (for 39 pages) or “ca.” (for approximately).

For this resource, several abbreviations appear in the Title (a transcribed field), so they are recorded as they appear on the resource:

245 10 ǂa For honor, glory & union : ǂb the Mexican and
    Civil War letters of Brig. Gen. William Haines Lytle /
    ǂc Ruth C. Carter, editor.

But could you include the unabbreviated version as a variant title?
