Affiliation Category is a main holding category for all sorts of affiliated authors, for example, Presbyterian, Baptist, Brethren, etc. Look under this category to see what we have.
Note: It is not always apparent what the affiliation of a work or author is, and as this is discovered, we will apply it. In the case of a set of works with each book written by a different author, we usually do not apply the affiliation category unless it is clear, Church of Christ, Brethren, etc.
