Speaking about the greater likelihood of preservation of photographic sources in comparison to “paper” ones, Bigazzi, referring to an essay by Luca Borzani, said: “It is clear that the most significant photographic records about industry are preserved by the customers of the photographer’s studios: the companies themselves. If we consider the systematic destruction of paper records, [usually] stopped too late, we have to admit that the photographic records generally had a better destiny. While some dispersion has occurred, the image of the industry had the ambiguous advantage that photography [seems to be an independent testament, exhaustive and concise at the same time, of something that happened in the past]. Also in the context of the company, which seeks to eliminate or reduce the space required [for records] and the management costs of anything unrelated to production, the [informative, effective and esthetic importance] attached to the photographs assured their preservation.” D.
