Evidence stage
DeploymentAn employer has put it into production. Can move the baseline — weighted by scale and how similar the setting is.
Tasks this bears on
Lending, returns and reservations
Checking items out and in, handling holds, and keeping the self-service kiosks and return chutes working — work librarians share with, and supervise, library clerks.

Keeping the shelves and stock in order
Shelving, checking shelf order, taking inventory, and removing worn or outdated items.

Where this applies
Singapore's public libraries, described by the head of innovation at the National Library Board, which runs them, in a paper for an international library meeting in 2019. It states that autosorters and shelf-reading robots are deployed at all libraries to handle the more repetitive tasks, that staff no longer station at library counters but rove to serve patrons, and that the automation initiatives save S$1.9 million a year. Returned items are sorted automatically, with manual intervention only for exception items, about 1% of returns; the shelf-reading robot scans RFID tags after closing, so staff need only attend to mis-shelved books, about 5% of the collection. It also says what the robot cannot do: it detects misplaced items better than staff but cannot pick them up and reshelve them, so it hands them over to staff. This is the operator describing its own libraries; the saving is its figure, stated as money rather than jobs, and the paper does not say how staffing changed.
What this means
In Singapore's public libraries the returns and the shelf-checking are done by machines, and staff were moved off the counter. What is left for people is the exceptions — the 1% of returns the sorter cannot place, the misplaced books the robot finds but cannot move — and the patrons themselves.
What it does not yet show
It is the operator's own account of one library system, with savings given in money; it does not say how many library jobs changed or how many other library systems work this way.
What you can check
Open the IFLA paper "Transforming Library Operation with Robotics" and find the line beginning "Autosorters and shelf-reading robots are deployed at all libraries".
Does it change the assessment?
No. The impact index is never moved by a single event. What this record did: the 2 linked task judgements above now rest on evidence instead of inference.
