web's way to refer to another document. However, it does not allow citing to offline sources and if the destination of the link changes, the link can become dead or irrelevant. A proposed solution is the use of a digital object identifier. In instances where a user needs to add an endnote or footnote using HTML, they can add the superscript number using <sup></sup>, then link the superscripted text to the reference section using an anchor tag. Create an anchor tag by using and then link the superscripted text to "ref1". History The London printer Richard Jugge is generally credited as the inventor of the footnote, first used in the Bishops' Bible of 1568. Early printings of the Douay Bible used two closely spaced colons (actually squared four dot punctuation mark U+2E2C “⸬”) to indicate a marginal note. Literary device At times, notes have been used for their comical effect, or as a literary device. James Joyce's Finnegans Wake (1939) uses footnotes along with left and right marginal notes in Book II Chapter 2. The three types of notes represent comments from the three siblings doing their homework: Shem, Shaun, and Issy. J. G. Ballard's "Notes Towards a Mental Breakdown" (1967) is one sentence ("A discharged Broadmoor patient compiles 'Notes Towards a Mental Breakdown,' recalling his wife's murder, his trial and exoneration.") and a series of elaborate footnotes to each one of the words. Mark Z. Danielewski's House of Leaves (2000) uses what are arguably some of the most extensive and intricate footnotes in literature. Throughout the novel, footnotes are used to tell several different narratives outside of the main story. The physical orientation of the footnotes on the page also works to reflect the twisted feeling of the plot (often taking up several pages, appearing mirrored from page to page, vertical on either side of the page, or in boxes in the center of the page, in the middle of the central narrative). Flann O'Brien's The Third Policeman (1967) utilizes extensive and lengthy footnotes for the discussion of a fictional philosopher, de Selby. These footnotes span several pages and often overtake the main plotline, and add to the absurdist tone of the book. David Foster Wallace's Infinite Jest includes over 400 endnotes, some over a dozen pages long. Several literary critics suggested that the book be read with two bookmarks. Wallace uses footnotes, endnotes, and in-text notes in much
