Canada Through the Lens: mapping a collection

This summer, to mark Canada's 150th anniversary celebrations, the British Library will be displaying a selection of photographs from its Colonial Copyright Photograph Collection under the title, 'Canada Through the Lens'. The photographs contained in the collection were received from Canada between 1895 and 1924 under legal deposit regulations and in 2012 the Library began to digitise this collection in collaboration with Wikimedia Commons and the Eccles Centre for American Studies.
Back in 2012 I was the curator for Canadian collections and so I thought that this year I would merge my old work with my new responsibilities by making a map of the material digitised in 2012. The Picturing Canada Project, as this work was called, was a successful attempt to release a collection online under Public Domain licensing but browsing material in the list-based structure of Wikimedia Commons can be laborious. Given most people who access the collection want to find photographs of places that interest them (for personal or research reasons) a map seemed like a good entry point and so we've been tinkering around with using the collection metadata to display an interactive map. The first results can be seen here:
The map has been built by inputting metadata relating to the collection (largely derived from original copyright records and work done by P. B. O'Neill of Dalhousie University in the 1980s) into a spreadsheet and then adding to this the best geographical coordinate data we could find. This data was then uploaded to Google Fusion Tables, which can produce a map as one of its software tools. When it comes to the geo-data sometimes we have been lucky and been able to pin a location accurately. However, in many cases we have roughly developed a location by tracing place names in the photograph title, while in others we have had to pin the location of the photographer's studio or make a best guess as to an appropriate location. As a result, the geographical data you see above is a good start but very much a work in progress.

Each point on the map corresponds to a photographic record and clicking on the icon will provide users with metadata on the image as well as a link to the image on Wikimedia Commons. In some instances there is no link as there is more work to do uploading a few files to Commons or removing metadata for images that were not digitised (for an explanation as to why, see the Picturing Canada project page). The colouration attributed to the icons is an attempt to visually depict when photographs were produced and each colour means the following:
- Yellow, 1895 - 1899
- Green, 1900 - 1909
- Red, 1910 - 1919
- Blue, 1920 - 23 (end of active period of legislation)
'Canada Through the Lens' will open at the British Library on May 26th so we have plenty of time to polish the map and its content ahead of the main release. As part of this, if any of you spot problems or have suggestions for refinements feel free to email me at: philip[dot]hatfield[at]bl[dot]uk.
