Welcome to the Catalogue of the Pontifical Gregorian University Library

What does it contain?
The catalogue contains the bibliographic records of all the Library's patrimony, both print and electronic, except for some document belonging to the Agiographic Fund, which are acquired but not yet catalogued, the Cyrillic section of the Wetter Fund, the single articles of the journals and the single electronic resources indexed in the databese subscribed. Electronic resources can be researched both through the catalogue or throuh DigiPoint, the Library platform that hosts also many open access resources, while electronic periodicals can be better searched through Full Text Finder, the virtual catalogue that indexes many open access titles together with the Library electronic periodicals and also all the periodicals available within the databes subscribed.

How are the resources described?
The records are in MARC21 format while the bibliographic description follows the AACR2 / RDA (Anglo American Cataloguing Rules / Resource Description and Access) rules, flanked by local variations drawn up and adopted by the URBE Network (Roman Union of Ecclesiastical Libraries). The classification system in use has been specially developed by the Jesuit Fathers and is designed to describe in depth all the disciplines studied at the Pontifical Gregorian University; it is therefore used exclusively in its Library. For the monographs the classification code is alphanumeric: its structure includes a numerical part that indicates the general discipline (the topic class) and an alphabetic part which allows to articulate this discipline (the subclass). For the periodicals the code is exclusively alphabetic and identifies disciplinary macro-areas. In both cases the classification code corresponds to a verbalization structured hierarchically according to the same criteria and inserted in a "Subject" field.

What features are available?
The Library catalogue allows four search modes: "Simple Search", "Advanced Search", "Search by Index" and "Search by Subject Area". In all cases, once the research has been launched, it is possible to further refine it using the available facets (Author, Language, Publication date, Subject, Subject class, Collection).

Simple search

Allows to search for documents with the help of auto-completion, using keywords present in any of the fields of the bibliographic record, or by selecting one of the three main fields in the drop-down menu (Title, Author, Subject).

Advanced search

Allows to search for documents using multiple fields at the same time; the search fields can be specified through the drop-down menus (Everywhere, Title, Author, Subject, Classification, Publisher, Holding notes, ISBN / ISSN, Location code, Record Nr.) and related by the Boolean operators AND (co-presence in the record of all the search terms entered), OR (presence in the record of one or more search terms), NOT (absence in the record of the search terms entered). It is also possible to further delimit the search using one or more filter fields (Collection, Language, Publication date).


Allows to consult the main indexes of the catalogue (Title, Name, Name/Title by name, Name/Title by title, Subject, Classification, ISBN, ISSN, Location code) that are proposed in lists arranged alphabetically. Once the index has been selected and the starting search term is inserted, the system displays a scrolling list that shows the number of bibliographic records associated with each item and indicates any forms of referral. To open records, just click on the item itself.

Search by Subject Area

Allows to carry out a research starting from the disciplinary areas covered by the collections; descending from the general to the particular through the tree structure, it is possible to visualize the rich thematic hierarchy, to derive research suggestions and, finally, to arrive at the documents that respond to one's study needs.
