Each text consists of a number of files, each of which is one version of the text. They might be transcriptions of manuscripts, of printed sources, or born-digital texts. They are encoded in TEI XML format, and the XML source can be viewed, by clicking the button, or downloaded, by clicking the button and selecting “TEI XML”.

In order to compare different versions of a text, you can generate an apparatus of variants:

• First, pick one version of the text to be the base text.
• Then, in the sidebar, click
• Select one or more other witnesses that you want to compare to the base text.

• Then, click

• The variant readings will appear in the right margin. Move the cursor over a variant reading in order to see the lemma highlighted in the base text.

• Click on a siglum to go to the transcription of that witness.
• A siglum with a dotted underline indicates the presence of a minor orthographic variation. Move the cursor of the underlined siglum to display it.
• In the text, click and drag to highlight a passage to show a positive apparatus.

• In the positive apparatus, click the button to show a variant matrix.

• Click the button, if available, to show a cladistic tree.
