Trading Consequences

About

The Trading Consequences search interface is designed to allow visitors to query the Trading Consequences database in order to retrieve potentially interesting historical documents relating to commodities and locations and the possible relationship between them.

There are two types of searches that can be performed:

Commodity Search

This performs a search of the database table of unique commodities for commodities beginning with the search term entered. The returned list of commodities is sorted by two criteria:

  • whether the commodity is a commodity concept 1
  • alphabetically

Selecting a commodity from the list of commodities takes the visitor to a page displaying:

  • Possible locations related 2 to the trade of the selected commodity, where each marker on the map displays the name of the location and the number of times this location/commodity relationship has been mentioned in a historical document. The visitor has the option of activating a heatmap layer on the map interface to aid in the identification of popular locations.
  • A list of historical documents and an indication of how many times the selected commodity is mentioned within each document.

The contents of the above two areas of the page can be filtered by selecting from the Collection and Decade filters on the left hand side of the page.

Selecting a document of interest from the list of documents takes the visitor to a page containing details of the selected document and a list of all the sentences within the document where the selected commodity 3 is mentioned. Additionally, if available, a link to a scanned copy of the page containing the sentence of interest is provided. 4

Location Search

This performs a search of the database table of unique locations for locations beginning with the search term entered. The returned list of locations is sorted by the number of times the returned location is mentioned within the historical documents.

Selecting a location from the list of locations takes the visitor to a page displaying:

  • General information about the selected location such as which country it is within, population etc.
  • A map highlighting the location with a map marker.
  • A list of historical documents and an indication of how many times the selected location is mentioned within each document.

The list of historical documents can be filtered by selecting from the Collection, Decade and Commodity filters on the left hand side of the page.

Selecting a document of interest from the list of documents takes the visitor to a page containing details of the selected document and a list of all the sentences within the document where the selected location and commodity (if the previous view was filtered by commodity) are mentioned. Additionally, if available, a link to a scanned copy of the page containing the sentence of interest is provided.

  1. A commodity concept is the unique label for a commodity and allows alternative labels for the same commodity to be searchable via the commodity concept.

    e.g. a search for Cinchona returns the commodity concept Cinchona which encompasses mentions of not only Cinchona but also Chinchona, Peruvian Bark etc.

  2. Locations mentioned in the same sentence as the selected commodity.

  3. If the selected commodity is a concept these commodity mentions may be alternative labels for the same commodity.

  4. Not all collections have scanned pages for documents and some of the collections have restricted access.
