Labbé's classification of books entitled _bibliotheca_ shows a remarkable understanding of their different kinds and calls attention to their remarkable variety. I cannot easily cite an equally instructive and suggestive review of bibliographies.[94] Labbé's classification is as follows: (1) _Bibliothecae_ named for places (_vel a locis dictae_): Augustana,[95] Floriacensis,[96] Ingolstadiensis,[97] etc.: (2) _bibliothecae_ named for persons (_vel a personis_): Borromaea,[98] Bodleiana,[99] Thuana,[100] etc.; (3) _bibliothecae_ named for rulers (_vel a principibus_): Regia Gallica,[101] Caesarea,[102] Bavarica,[103] etc.; (4) _bibliothecae_ named for religious orders (_vel a Ordinibus Sacris_): Augustiniana,[104] Carmelitica,[105] etc.; (5) _bibliothecae_ named according to the subjects with which they deal (_vel a materia quam tractant_): Chymica,[106] Concionatoria,[107] Juridica,[108] etc.; (6) _bibliothecae_ named according to their arrangement or like circumstances (_vel a forma similibusve circumstantiis_): Classica,[109] Selecta,[110] Universalis.[111] The anonymous author of _The Newly Opened Library (Die neu-eröffnete Bibliothec), in which good information about libraries as well as convenient directions for acquiring, maintaining, and using them are put into the hands of students and inquiring friends. To which are added: the chief European libraries and what travelers ought to notice in visits to them_ (1702) hit upon the same idea of listing _bibliothecae_.[112] In this book a special section or appendix labelled "A List of Authors Who Have Written Books Entitled 'Bibliotheca' and Books about Libraries (Series Authorum qui Bibliothecas & de Bibliothecis scripserunt)" names books called _bibliotheca_, catalogues of libraries, and treatises on library science. The selection is obviously even more definitely bibliographical in character than Labbé's list had been. The compiler arranges the titles alphabetically according to the author's last names or, in the case of an anonymous work, according to an important word in the title. This arrangement and the choice of titles show that he had no knowledge of Labbé. Like Labbé, he includes none of the collections of texts that were entitled _bibliotheca_. Our author begins with Valerius Andreas, _Bibliotheca Belgica_ (1643), a biobibliographical dictionary of writers in the Low Countries. In the letter "A" he includes the _Augustanae Bibliothecae Catalogus_ (1633), which he also enters under the name of the compiler, Elias Ehinger, librarian at Augsburg. He cites the _Bibliothèque universelle_, a critical journal edited by Jean Leclerc, because the title contains the word _Bibliothèque_. Such titles show that he was thinking in bibliographical terms, for Andreas's book and the Augsburg catalogue are bibliographies and Leclerc's journal was a review of current publications.
