This is an old revision of the document!
We’re in the process of updating the documentation for Zotero 5.0. Some documentation may be outdated in the meantime. Thanks for your understanding.
How can I see how many items I have in my Zotero library?
To see how many items you have, click an item in the middle pane and Select All (Command-A on macOS or Control-A on Windows/Linux). A count of selected items will appear in the right-hand pane.
To determine total items, including child attachments and notes, click an item and press the + (plus) key to expand all parent items before using Select All. You can press - (minus) afterward to collapse all items.
