Following an enquiry, it came to light that a collection of several hundred glass slides in the basement of Sheffield Central Library had been deposited, probably in the 1930s, and never looked at since. They had belonged among others to Society Secretary James Ragg Wigfull, a Sheffield architect who was also a very keen photographer; the quality of many of the pictures is outstanding. A group of Hunter members worked on cataloguing the slides and identifying those that were not labelled; any not on Picture Sheffield were then be scanned and added.
