This interface allows users to compose virtual editions of the Quixote. The copies of all editions in the variorum have been collated and all variants have been identified, classified and annotated. Users can select editions and chapters and then access the unedited text (documentary text) or the same text edited by a particular editor.

Users may customize the virtual variorum edition by selecting categories of variants and inclusion of annotations and/or emendations to compose their own editions. The existing variants and emended texts are color coded according to their categories. Cliking on any of the variants, emendations and annotations opens another window showing their specific details and information.

The unedited text shows only the variants resulting from the collation between the base text and all other copies. Clicking on the highlighted variants shows the complete list of variants present on the collation. Users can click on the Folio numbers shown in the text to navigate to the browsing display to further check readings in the facsimile editions.
