Concordances, consisting of the words of the Bible detached from their context, form a convenient link with Commentaries. The latter fall into two principal sections, according as they relate to Scripture in its entirety or to some particular part. In arranging the former, the erudite labours of scholars are, as far as possible, kept apart from the popular illustrative literature of modern days. The order of commentaries on separate books must, of course, correspond with that of the books themselves in the canon of the Bible.
Next succeeds the very important class of literature representing the Bible in contact with society through the medium of the Church. The most obvious form of this relation is the liturgical. Liturgies accordingly succeed Scripture in the Museum arrangement, precedence being given to the various Churches in the order of their antiquity.
