How to perform batch updates of literature in Zotero?

Batch updating literature in Zotero efficiently modifies metadata for multiple items simultaneously. This capability is inherent within Zotero's interface or via scripts like Zotero plugins, significantly enhancing workflow when managing large libraries. Batch updates are achieved primarily through Zotero's item pane. Select multiple items (using Ctrl/Cmd+Click or Shift+Click) in the center pane. Key metadata fields visible in the right-hand info panel become editable simultaneously for all selected items. Changes made here apply immediately to every selected item. Utilising parent items or collection settings can indirectly propagate changes to child items. For highly complex or automated batch tasks, JavaScript scripting (available through plugins) provides powerful options, while direct database modification is generally discouraged. To execute a batch update, first select the desired items within your Zotero library. Access the right-hand info panel; editable fields common to all selected item types will be visible. Input the new metadata values into the appropriate field(s). For more intricate updates, explore dedicated plugins offering enhanced batch editing capabilities or employ JavaScript scripting through Zotero's advanced functions. Subsequently, right-click on the library or collection and select "Refresh" to ensure all metadata is correctly updated and synced across devices.
