Locate Menu

The Locate menu offers several ways to access files in your library and to look up items online. The menu can be opened by clicking the straight arrow button () at the top-left of the right-hand column of the Zotero pane.

Which menu entries are available depends on the type of items you have selected in the middle column. The possible options are:

Library Lookup

If you select the Library Lookup option, Zotero will try to locate your items in an online library catalog, so you can track down a physical or online full-text copy of the resource. By default, Zotero uses the OpenURL service of, but you can specify a different OpenURL resolver (e.g., the OpenURL resolver of your local university library) in the Advanced tab of the Zotero preferences. Most university libraries provide their OpenURL resolver link on their websites. A list of OpenURL resolver links is also available here.

Managing Lookup Engines

The “Manage Lookup Engines…” option opens the Article Lookup Engine Manager window, where you can enable/disable lookup engines, remove installed lookup engines, or reset your installed lookup engines to the defaults.

It is not currently possible to add new lookup engines using through either the Zotero desktop client or the browser Connector extensions. To add new lookup engines, you must edit the engines.json file located in the locate folder in your Zotero data directory. Lookup engines can be added to this file using JSON syntax specifying an OpenSearch lookup engine. A more user-friendly way to add lookup engines will be added in a future version.

An engines.json file with a variety of useful lookup engines is available from To use this file, download it and open it. Remove any lookup engines you don't need, then save. Place the file in the locate folder in your Zotero data directory (replacing the version of engines.json that is already present).

Public Library Lookup Engines

A repository of thousands of local public library Lookup Engines (as well as engines for some universities and commercial databases) is available from
