Below Ben Myers shares his different types of reading.  His are different than mine, but there is some similarity.  Mine roughly fit under the acrostic GROWTH:

GREATS (CLASSICS)

REVIEW (OR INTERVIEW)

OTHER (CATCHALL FOR THOSE THAT DON’T FIT IN THE OTHER CATEGORIES)

WORD (BOOKS RELATED DIRECTLY TO THE BIBLE LIKE COMMENTARIES)

TEACHING (BOOKS THAT RELATE TO SOMETHING I AM TEACHING)

HISTORY
