Exporting or suppressing “Retrieved DATE” for select item types to comply with APA7

BLUF. To export “Retrieved DATE,” leave the date field blank. To suppress exporting of “Retrieved DATE,” enter “n.d.” without quotation marks in the item’s date field. This solution works for at least Dictionary Entry, Encyclopedia Article, or Web Page item types. Please post any success, failure, or recommendations for improving this solution. See below for additional details.

Issue. How to force Zotero (6.0.8) to export or not export “Retrieved DATE” in <Create Bibliography from Item…Output Mode: Bibliography> and the <Add/Edit Bibliography> function in the word processor plugin for <Item Type:> Dictionary Entry, Encyclopedia Article, or Web Page when the item does not have a date of publication?

Discussion. Section 9.16 of the Publication Manual of the American Psychological Association, or the Concise Guide to APA Style, 7th Editions (APA7) requires a “Retrieved DATE” for some web pages and reference entries that do not have a date of publication but not for others. APA7 (2020) instructs, “Provide a retrieval date in the source element when citing an unarchived (i.e., not stable) work that is likely or meant to change” (p. 290). APA provides some examples in Chapter 10 (33, 47,104, & 106). See Reference Examples on apastyle.apa.org for additional examples.

Unless there is a Citation Style Language (CSL) specification I am not aware of and with which all websites complied, there does not seem to be an automatic process for Zotero to decide when to include “Retrieved DATE.” So, Zotero users will have to apply their best judgment and manual data editing to force compliance with APA7. Luckily, there is an easy method to do that.

Solution. For items without a publication date that require a “Retrieved DATE,” leave the <Date> field in the Zotero item blank. Leaving the date field blank will force Zotero to include the retrieval date in bibliographic output while still including “n.d.” in the date element, as shown in Example 1.

Example 1. <Date> = blank

For items without a date of publication that do not require a “Retrieved DATE,” enter “n.d.” without quotation marks in the <Date> field of the Zotero item. Entering “n.d.” in the <Date> field will cause Zotero not to output a “Retrieved DATE,” as shown in Example 2.

Example 2. <Date> = n.d.

I have tested the above solutions for <Create Bibliography from Item… > in Zotero 6.0.8 on Windows 11 and the <Add/Edit Bibliography> function in the Word 365 plugin for <Item Type:> Dictionary Entry, Encyclopedia Article, and Web Page. Please post any successes or failures you had for other configurations, item types, or citation styles. Also, please share any comments or recommendations for a more efficient solution to this issue.

    The retrieval date is only included in APA style references if the item has a URL and it has neither a publication date or a status. This is intended to align with APA’s rule that the retrieval date should be included if the website is updated frequently. If the item is a web item with no publication date, this seems to be a reasonable way to automate that rule

    You can alway delete the access date from your data to omit

    @bwiernik - Thank you for the reply. On a related note, when will Zotero include an item type for datasets as described in https://www.zotero.org/support/dev/translators/datasets? Your interim solution using the Document item type was very helpful.

    Just as background for other readers, APA also says to include the retrieval date for data sets if that data set is designed to change over time (e.g., if data are still undergoing collection)" (APA PM § 10.9 - Data Sets).

    Below are some other examples on when a retrieval date is needed from Chapter 10 of the APA Publication Manual.

    Example 14 - [Journal] Article from the UpToDate database

    Example 33 - Dictionary, thesaurus, or encyclopedia

    Example 47 - Entry in a dictionary, thesaurus, or encyclopedia, with group author

    Example 48 - Entry in a dictionary, thesaurus, or encyclopedia, with individual author

    Example 49 - Wikipedia entry (if no permanent link)

    Example 75 - Data set

    Example 76 - Unpublished raw data

    Example 100 - Map

    Example 104 - Twitter profile

    Example 106 - Facebook page

    Example 114 - Webpage on a website with a retrieval date
