A medida que construyes tu biblioteca Zotero, puedes introducir algunos elementos duplicados. Por ejemplo, podrías haber guardado el mismo artículo dos veces de una paǵina web, o artículos importados que ya estaban en tu biblioteca. Afortunadamente, Zotero puede ayudarte a identificar posibles duplicados y te permite combinarlos.

Clicking on the “Duplicate Items” collection in your library or right-clicking the library in the left column and selecting “Show Duplicates” will show the items Zotero thinks are duplicates in the center column.

Zotero currently uses the title, DOI, and ISBN fields to determine duplicates. The algorithm will be improved in the future to incorporate other fields.

In the “Duplicate Items” collection, select an item in the center column. Zotero will automatically co-select the other items that it thinks are duplicates. Click the “Merge n Items” button in the right column to merge the items.

You can also select a group of two or more items of the same item type anywhere in your Zotero library, right-click, and select “Merge Items…” from the context menu.

Merges are automatically recognized by the word processor plugins and don't affect your automatically generated citations and bibliographies.
