-Reconciliation is the process of matching your dataset with that of an external source. Datasets for comparison might be produced by libraries, archives, museums, academic organizations, scientific institutions, non-profits, or interest groups. You can also reconcile against user-edited data on [Wikidata](wikidata), or reconcile against [a local dataset that you yourself supply](https://github.com/OpenRefine/OpenRefine/wiki/Reconcilable-Data-Sources#local-services).

 Other services may exist that are not yet listed in these two places: for example, the [310 datasets hosted by the Organized Crime and Corruption Reporting Project (OCCRP)](https://aleph.occrp.org/datasets/) each have their own reconciliation URL, or you can reconcile against their entire database with the URL [shared on the reconciliation API list](https://reconciliation-api.github.io/testbench/). For another example, you can reconcile against the entire Virtual International Authority File (VIAF) dataset, or [only the contributions from certain institutions](http://refine.codefork.com/). Search online to see if the authority you wish to reconcile against has an available service, or whether you can download a copy to reconcile against locally.

 For matched values (those appearing as dark blue links), the underlying cell value has not been altered - the cell is storing both the original string and the matched entity link at the same time. If you were to copy your column to a new column at this point using `value`, for example, the reconcilation data would not transfer - only the original strings. You can learn more about how OpenRefine stores different pieces of information in each cell in [the Variables section specific to reconciliation data](expressions#reconciliation).
 
-For each cell, you can manually “Create new item,” which will take the cell’s original value and apply it, as though it is a match. This will not become a dark blue link, because at this time there is nothing to link to: it is a draft entity stored only in your project. You can use this feature to prepare these entries for eventual upload to an editable service such as [Wikidata](wikidata), but most services do not yet support this feature.
