Metadata correction proposals

* *Discipleship Journal* - missing covers, despite them being in the resource

* *An Exegetical Summary of Philippians* - 1st edition is missing series name

* *God, Revelation and Authority* - bibliographic citation gives author as Carl Ferdinand Howard Henry, but he's listed as Carl F. H. Henry in the author field, and the latter is what he's universally known by in his publications; I suggest you change it in the bibliographic citation.

* *Grace Abounding to the Chief of Sinners* - incorrect publication date (both editions)

* *Grammars with Subject O.T. or N.T.* - please remove as per other Grammars -> A Biblical Hebrew Reference Grammar, Greek New Testament Insert, Hebrew Bible Insert.
