Robot librarians to replace book “stackers?”

According to this story in the Toronto Globe and Mail a robotics laboratory in Spain is working on a prototype of a robot librarian.

It is to come with a speech-recognition and seeing capacity that should allow it to make out the name of a book when spoken to it and to identify the title on the shelves. When it becomes mobile, it will deliver the book to the eager reader.

Lots of other tidbits about similar librarian-replacement projcts happening around the globe.

One question for our northern pals: Is “stacker” another name for shelver?
