Unger's account of forty-one theological bibliographies and collections of texts entitled _bibliotheca_ is not altogether bad. He often quotes the titles of chapters from these books or says that a book is a collection of texts and not a bibliography. Much of this information was even then available in well-organized reference works, and Unger's only contribution is the selecting of the books entitled _bibliotheca_. His account of legal bibliographies begins with Martin Lipenius, _Bibliotheca juridica_, "which was published at Frankfurt in 1607 as a folio and was enlarged by F. G. Struve in 1720." This is not a good start, for the first date is wrong (it should be 1679) and he would have found five more legal bibliographies entitled _bibliotheca_ by opening Lipenius. In this category he cites nine more titles, counting three works by Caspar Thurmann as one book. This combination is not particularly objectionable. Thurmann had made a classified legal bibliography and finding no publisher, had printed portions as small bibliographies. Unger then proceeds to historical, medical, and philosophical categories, but we need follow him no further. He finally resigns himself to naming titles in a confused order. His disappointing performance has the merit of naming books called _bibliotheca_, but it does not suggest, as Labbé and the anonymous author of _Die neu-eröffnete Bibliothec_ had done, that they were primarily interesting as bibliographies. The sixty folio pages (double columns) filled with entries beginning with the word _bibliotheca_ in Michael a San José, _Bibliographia critica_ (1740-1742) have the appearance of a list of books, but on closer examination many titles prove to be made up. In other words, San José offers what amounts to a general survey of bibliography. Since his book is almost unknown and the entries are often curious, a brief description will not be out of place. The articles are arranged alphabetically according to the adjective that follows the word _bibliotheca_. Thus, the list begins with J. F. Reimann, _Bibliotheca acroamatica_ (Hannover, 1712), a condensation of Peter Lambeck's catalogue of manuscripts in the Imperial Library at Vienna. The next entry consists of two columns headed "Bibliotheca Adriani Baillet" and is a brief discussion of the _Jugemens des savans_ (1685-1686) and a long summary of a prospectus of a philosophical dictionary that Baillet planned but never published. More entries follow in an alphabetical order according to proper names or adjectives derived from proper names or the subject matter. Laurentius de Cremona, _Bibliotheca aethiopica_ is entered under "Aethiopica," and Albert Bartholin, _Liber de scriptis Danorum_ under "Alberti." It is difficult to discover the plan of arrangement, and equally difficult to see the reasons for choosing the books. The presence of more than twenty entries entitled "Bibliotheca Biblica" is not surprising, but
