<!-- Contents:
APA uses four main reference elements:
1. Author (APA 9.7-12)
2. Date (APA 9.13-17)
3. Title and descriptions (APA 9.18-22)
3.1. Title (APA 9.18)
3.2. Identifier (in parentheses) (APA 9.19)
3.3. Description [in square brackets] (APA 9.21-22)
4. Source (APA 9.23-37)
4.1. Serial sources (APA 9.25-27)
4.2. Monographic sources (APA 9.28)
4.3. Publisher sources (APA 9.29)
4.4. Database and archive sources (APA 9.30)
4.5. Works with specific locations (APA 9.31)
4.6. Social media and website sources (APA 9.32-33)
4.7. DOI or URL (APA 9.34-36)
A note on the source may follow the main reference elements:
5. Publication history (APA 9.39-41)
APA also provides parallel rules for legal references following The Bluebook: A Uniform System of Citation (chap. 11):
6. Legal references
-->
<!-- APA categorizes all sources as serial (APA 9.25-27) or monographic (APA 9.28).
Serial
: article-journal article-magazine article-newspaper periodical post-weblog review review-book
Serial or Monographic
: interview paper-conference
Monographic with any of `collection-editor compiler editor editorial-director`.
A serial `paper-conference` is unpublished if it lacks any of `issue page supplement-number volume`.
Monographic
: article book broadcast chapter classic collection dataset document entry entry-dictionary entry-encyclopedia event figure graphic manuscript map motion_picture musical_score pamphlet patent performance personal_communication post report software song speech standard thesis webpage
Legal
: bill hearing legal_case legislation regulation treaty
-->
<!-- Equivalencies:
`classic` == `book`
`document` == `report` (but give full date)
`standard` == `report`
`performance` == `speech`
`event` == `speech`
-->
<!-- Role equivalencies:
`compiler` == `editor`
`organizer`, `curator` == `chair`
`script-writer` == `director`
`producer` == `director` (but don't print both)
`guest`, `host` == `director`
`series-creator`, `executive-producer` == `editor`
-->
<!-- Reviews are detected if an item has type `review` or `review-book` or if it has any of the variables `reviewed-title`, `reviewed-author`, or `reviewed-genre`. For the latter case, reviews are commonly stored as types `article-journal`, `article-magazine`, `article-newspaper`, `post-weblog`, or `webpage`. -->
<!-- Indigeneous knowledge: Assume the item is stored as `document` or `speech` and that Nation/Community, treaty territory, where the Elder lives, and topic are all stored in `title`. Cf. <https://libguides.norquest.ca/c.php?g=314831&p=5188823>. If the item is stored as `interview`, assume that Nation/Community, treaty territory, and topic are stored in `title`. 'Oral teaching' or similar is stored in `archive`, and where the Elder lives is stored in `archive-place`. -->
