You're welcome to work on your own projects, but if you're looking for things to work on, consider working on Wikidata WikiProject COVID-19 and adding references as part of the #1Lib#1Ref Campaign.

References

Most statements on Wikidata should be verifiable in some source of information. They point to a source that supports the data in a statement. References have a property and value like statements. The value is the source. The property is usually:

  stated in (P248) for publications and media
  reference URL (P854) for websites and online databases

References are not required in some circumstances:

• Statement represents common knowledge that isn’t disputed

 George Washington (Q23) → instance of (P31) → human (Q5)

• Statement refers to an external source of information that can be easily verified

 Mary Jo White (Q6779939) → ISNI (P213) → 0000 0000 4948 7201

• Item itself is a source for the statement

References for Websites

The most common sources in Wikidata are probably websites. Use reference URL (P854) with the website as the value and retrieved (P813) with the date you accessed the website.

Helpful Resources about References

• Help:Sources includes a good overview as well as steps for adding different types of resources as sources.
• LD4 Wikidata Affinity Group slides on references includes steps for adding an article and a book as a source for a reference.
• Stanford Libraries page on references including a list of properties used with references
• DuplicateReferences and currentDate gadgets

Ways to Contribute

Add references to authors who have published papers on COVID-19

1. Find authors using this query:

The following query uses these:

• Items: SARS-CoV-2 (Q82069695)   , COVID-19 (Q84263196)   , COVID-19 pandemic (Q81068910)   , scholarly article (Q13442814)   

• Properties: instance of (P31)   , main subject (P921)   , author (P50)   , publication date (P577)   

  SELECT DISTINCT ?author ?authorLabel ?pdate
  {
    VALUES ?topics { wd:Q82069695 wd:Q84263196 wd:Q81068910 } 
    ?item wdt:P31 wd:Q13442814.
    ?item wdt:P921 ?topics.
    ?item wdt:P50 ?author.
    OPTIONAL { ?item wdt:P577 ?pdate }
    SERVICE wikibase:label { bd:serviceParam wikibase:language "en" } .
  }
  ORDER BY ?pdate

2. Choose items and look for statements that don't have references. Try to find references to support statements that need them.

3. If you find useful sources and would like to enhance the author item by adding statements, the Stanford Libraries Wikidata WikiProject has a helpful list of properties for academic faculty that can also apply to researchers in general.

Add references to items for people with archives at your institution

  WHERE
  {
