Methods of circulation control, using the Newark Charging System as a prototype, are reviewed. Two criteria for a charging system in a university and special library are that it must show both location and due date of materials taken out of the library. The transaction card, charging machine, punched card, and computer are devices designed to speed up conventional procedures. They are described and evaluated according to the aforementioned criteria.

Astronomers have long tracked double stars in efforts to find those that are
gravitationally-bound binaries and then to determine their orbits. Early
catalogues by the Herschels, Struves, and others began with their own
discoveries. In 1906 court reporter and amateur astronomer Sherburne Wesley
Burnham published a massive double star catalogue containing data from many
observers on more than 13,000 systems. Lick Observatory astronomer Robert Grant
Aitken produced a much larger catalogue in 1932 and coordinated with Robert
Innes of Johannesburg, who catalogued the southern systems. Aitken maintained
and expanded Burnham's records of observations on handwritten file cards, and
eventually turned them over to the Lick Observatory, where astrometrist
Hamilton Jeffers further expanded the collection and put all the observations
on punched cards. With the aid of Frances M. "Rete" Greeby he made two
catalogues: an Index Catalogue with basic data about each star, and a complete
catalogue of observations, with one observation per punched card. He enlisted
Willem van den Bos of Johannesburg to add southern stars, and together they
published the Index Catalogue of Visual Double Stars, 1961.0. As Jeffers
approached retirement he became greatly concerned about the disposition of the
catalogues. He wanted to be replaced by another "double star man...
