The definition of “list” is problematic—“a simple series of words or numerals” (Merriam-Webster), “a number of connected items or names printed consecutively” (Google), “a series of names or other items written or printed together in a meaningful grouping or sequence so as to constitute a record” (dictionary.com). Nowhere is finality mentioned. Thus, a list, by definition (or lack thereof), is open-ended. In other words, you can always add more to the list. Italian author Umberto Eco touched upon the conundrum of cataloguing in his 2009 Louvre series “Vertigo of Lists.” Borges, too, was an avid list maker and did so with ample brushstrokes of irony and play.
