======Locate Menu======

{{ :locate:locate-menu.png?direct&|}}

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 ({{:locate:toolbar-go-arrow.png?direct&|}}) 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:

  * **View File/PDF/Snapshot** - open the files/PDFs/snapshots of the items
  * **View Online** - look up the items online, using its URL, DOI, or child link's URL
  * **Open in External Viewer** - as "View File/PDF/snapshot", but opens outside of Firefox (Zotero for Firefox only)
  * **Show File** - locates the files/PDFs of the items on your computer
  * **Library Lookup** - looks up the items in your library of choice using OpenURL
  * **CrossRef Lookup** - looks up and resolves the DOI of the items
  * **Manage Lookup Engines…** -- See [[#Managing Lookup Engines]]

===== 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 [[http://en.wikipedia.org/wiki/OpenURL|OpenURL]] service of [[http://www.worldcat.org/|WorldCat.org]], but you can specify a different OpenURL resolver (e.g., the OpenURL resolver of your local university library) in the [[preferences/advanced#openurl|Advanced tab]] of the Zotero [[preferences]].
===== Managing Lookup Engines =====

The Manage Lookup Engines… option opens the Article Lookup Engine Manager window, which allows you to enable/disable, reset, or remove installed lookup engines. Additional lookup engines can be installed via the 'Add "... Lookup"' entry that appears in the Locate menu when visiting a webpage that [[/support/dev/creating_locate_engines_using_opensearch|specifies a lookup engine via OpenSearch]].
