MARC fields. Typically, two separate traits would be described using two different terms, one for ethnicity or culture and a second for nationality. The term “African Americans” is in the ethnic/cultural category but also describes a nationality. Therefore, the term “Americans” will also be included in a record. There is also no LCDGT for the occupation writer or author because creation of a bibliographic record is based on literary warrant. The overwhelming majority of entries in the Name Authority File (NAF) and bibliographic records are by writers, making that criteria nearly useless for sorting. Wikipedia lists cover many topics, but lists of people often seem to combine the criteria of nationality and profession (Puerto Rican comedians, for example). In order for library catalogs to incorporate Wikipedia lists into search results, these different approaches will need to be reconciled. Depending on how difficult this is, libraries may instead choose to incorporate information from Wikidata items or lists generated and automatically updated by tools such as Listeria (Manske, 2015). It may be easier for Wikipedia to generate lists from library records, as they can combine the individual facets to form a list with as many characteristics as desired. This may also indicate a difference in design philosophy with librarians expecting users to utilize facets to narrow search results
