CERN the European Council for Nuclear Research has accumulated about a quarter of a million hard-copy images in its archive and they need captioning. Some 120,000 black and white images from the period 1955-1985 are currently being digitised, with files being uploaded in batches of several hundred per week. They are then automatically sorted into albums based on the existing information.
In most cases, at least some descriptions exist, allowing us to identify the pictures.
However, many albums are still in need of titles, the names of the people in the photos, descriptions of equipment, etc… help them here
