Enter the universities of the European continent and of Central and South America under the name of the place; all other societies under _Königliche_, _Herzogliche_, etc.
Cross-reference from the first word in the university names and from the place of societies.
A few learned academies, commonly called by the names of the cities where they are established, may be entered under the place with a cross-reference from the name. These are _Berlin, Göttingen, Leipzig, Lisbon, Madrid, Munich, St. Petersburg, Vienna_.
Enter national libraries, museums, and galleries, as well as libraries, museums, and galleries instituted or supported by a city, under the place, provided they have not a distinctive name.
Example of place: _Paris Bibliothèque Nationale_. _Boston Public Library._
Example of name: _Berkshire Athenæum_; _Boston Athenæum_; _British Museum_; _Forbes Library_; _Marucceliana, Biblioteca_; _Reuben Hoar Public Library_.
Enter observatories under the name of the place: e.g., _Greenwich, Observatory_. _Pulkowa, Sternwarte_; except that:
(_a_) University observatories go under the university: e.g., _Harvard College. Astronomical Observatory, at Cambridge._ (Cross-reference from _Cambridge_.)
(_b_) Any observatory having an individual name may go under that: e.g., _Lick Observatory_, _Yerkes Observatory_.
Enter expositions under the place where they were held: e.g.,
_Buffalo, Pan-American Exposition, 1901_; _Chicago, World's Columbian Exposition, 1893_; _New Orleans, World's Industrial and Cotton Centennial Exhibition, 1884-85_; _Philadelphia, Centennial Exhibition, 1876_.
Enter American State universities and State historical, agricultural and medical societies, whether supported by the State or not, under the name of the State, unless they are better known by a distinctive name. The State's name usually enters into the name of these societies and they are known outside of the State by its name. Cross-reference when necessary.
Enter churches under the name of the place.
Single churches have usually been entered under the place, a practice which arose in American indexes from our way of naming churches "The First Church in----," "The Second Church of----," etc., and applies very well to a majority of English churches, whose name generally includes the name of the parish. It is more in accordance with indexing principles to limit the local entry of churches to _First Church_, etc., and those which have only the name of the town or parish, and to put all others (as _St. Sepulchre's_, _St. Mary Aldermansbury_) under their names, as they read, and to treat convents and monasteries in the same way; but the convenience of having a single definite rule has been held to outweigh in this case the claims of consistency.
