Edmargin provides a very simple design for critical editions. There are predefined endnote sections for textual notes, explanatory notes and emendations. Markers in the text may be either traditional footnote marks (distinctive for each series) or marginal references to the page in the endnotes section where the comment is to be found. Endnotes can be set either as individual notes or as block paragraphs (for cases in which there are many small notes). Endnote sections have headers of the form "Textual notes to pp. xx--yy." New endnote sections can be defined on the fly. This material is subject to the LaTeX Project Public License.
