The metadata of automatically saved items may contain errors. Click on the information you want to change in the right column of the Zotero pane: a text box will appear, allowing you to edit the text. You can change the item type using the drop-down menu at the top of the pane. You can add or delete creators by clicking on the plus or minus signs, and you can change the creator type (author, contributor, etc.) by clicking on the type label to the left of the name. Clicking the single or double boxes to the right of the name toggles between a single field (for some Asian names, organizations, etc.) and double fields (lastname, firstname).
