  • Unique features of the CAG-online

    • The base texts of the CAG-online have been assembled from the best available printed editions – critical ones where possible. Their misprints have, for the most part, been corrected. The recently discovered Sermones Dolbeau and Sermones Erfurt have been incorporated as well as the letters, edited within the Augustinian corpus, but not written by Augustine himself.
    • Part of the CAG-online is, furthermore, a detailed and complete list of Augustine’s works, regarded as decisive for Augustinian research, including authentic titles, abbreviations and recent editions as well as ancillary information about Augustine’s Epistulae and Enarrationes in Psalmos.
    • Every word form occurring in a text is lemmatised, i.e. it is categorized under its grammatical base form and will be found by a search request for this form. All Augustinian quotations, taken from the Bible, ancient literature or his own works, are designated as such in categories, and their sources are duly recorded; quotations from Greek appear in Greek letters.
    • The retrieval software providing numerous possibilities of enquiry and indices was developed by the Competence Centre for Electronic Text Publishing at Trier University. The intuitive user guidance with extensive help functions is currently available in a German and an English version; other languages are being prepared.
    • Furhermore, the CAG-online provides comfortable access to a data base of Augustinian primary and secondary literature, currently comprehending ca. 33,000 bibliographical data records, developed with regard to content.
    • Maintenance, updating and continuous improvement of the data stock are to be ensured by the Zentrum für Augustinus-Forschung at Würzburg University (ZAF). For CAG-online subscribers the relevant updates are available at zero extra cost.
  • The significance of lemmatisation for the users of text databases

    Info: Lemmatisation is a linguistic procedure which assigns by means of numerical codes an actual word form appearing in a text to its grammatical base word form.

    Disadvantages of non-lemmatised databases

    Example: Search inquiry for ‹lex, legis› (= law) in the Augustinian oeuvre in conventional non-lemmatised databases:

    Possible strategy 1: Request for lex and for leg*

    Problem: You will find, additionally to ‹lex›, any inflected forms, but also any forms of the present stem and the perfect stem active of ‹legere› (= to read). Also derivates of ‹legalis, -e› or ‹legitimus, -a, -um› etc.

    Possible strategy 2: Entry of any forms of ‹lex›:

    Problem: You will have to search for 8 different forms, whereas you will have to take in consideration the overlapping with 4 forms of the verbum ‹legere›, which must be sorted out from the research result.

    lex  leges  lex leges
    legis legum legis legum
    legi legibus legi legibus
    legem leges legem leges
    lege legibus lege legibus


    Advantages of lemmatised databases

    Example: Search inquiry for ‹lex, legis› (= law) within the Augustinian oeuvre by means of the lemmatised text database of the Corpus Augustinianum Gissense a Cornelio Mayer editum (CAG-online):

    Entry of l:lex

    Result: Within some seconds you will find any of the 8.000 word forms of ‹lex› exclusively – identical forms of other words are not to be included.
