Image of text view, showing the Table of Contents of writings by Egderus. The name of the TOC is in black, beneath that a direction: <Select title.> Beneath that the first four titles appear in green, the last two in blue.

Here’s what the reader would see after clicking “Egderus” in the Inventory on the previous slide — i.e., a sub-TOC of that author’s writings, in that author’s peculiar font. The color coding of text displayed at this level specified the different kinds of writing in the whole work: red for apparatus, black for text in the writing itself, green for titles of writings on the default path, blue for writings not on the default path.
