Recap of Session
#120:

Zotero

• Imp/Ex–porting
• &
• Styles
• typst

1. ISBN, DOI (or other) identifier
2. FileImport... – then find your .bib file(s)
3. browser extensions/ connectors

Both have identical interface within the visual editor(s)

However – Zotero needs to be OPEN for Positron use – R Studio will find entries regardless of whether Zotero is currently open or not

1. Find desired style (use Style Search)
2. Click hyperlink to download
3. Place in project directory
4. Call out within YAML

Note

10,840 styles listed on Zotero Style Repository
