The shelving arrangement of the Wagga Wagga Daily Advertiser 1876–1950. Journal articles from 1960 to 1972 were stored on the opposite facing shelves. More recent Journals to present day were stored on the ground floor in similar shelving. The rather brittle nature of editions especially from 1912 to 1950 mean that the sourcing and adjustment of the journals was easier for the measurements with the conventional spectroradiometer and only a smaller sample of journals were used for smartphone measurements
