Located at the Université Catholique de Louvain, the Centre de Traitement Electronique des Documents' CD-ROM of Christian Latin Texts is part of an ongoing project to produce a database of Patrological texts covering authors of the 4nd through 15th centuries. The CLCLT-4 CD-ROM contains the complete Latin texts of the Corpus Patrum Latinorum (including the Corpus Christianorum, Series Latina, and the Continuatio Mediaevalis), as well as the Vulgate, Pseudepigrapha of the Old Testament, the complete works of Augustine, Jerome and many others. The CLCLT-4 Windows interface allows users to perform complex searches on all texts in the CLCLT-4 library. Search information can be downloaded to diskette or printer for later use.

Getting Started

Getting Started To access CLCLT-4 from a LETRS PC, double click on the CLCLT-4 icon in the Electronic Texts folder on the Windows desktop. CLCLT-4 provides help screens in one of 4 languages (English, French, German, and Italian) and you must choose a language before CLCLT-4 will fully load. When a language has been chosen, CLCLT-4 will display the VOLUMEN screen from which you may choose the CD-ROMs you wish to access. By default, CD-ROM 1 and 4 are automatically selected. Choose the volume(s) you wish to access and hit the Enter key. The INQUISITIO window will then appear.

The INQUISITIO window contains the main filter fields (Auctor, Titulus, Clavis, Aetas, Formae). These are the fields in which you enter the data to conduct searches on authors and works. First, let's have a look at the search language and how to "ask" CLCLT-4 to find what you are looking for in a text.
N.B. : Notice that each screen (e.g. VOLUMEN, INQUISITIO) is labelled with a Tab. You can move between windows by clicking on the labelled Tab, the Tab will then be highlighted and its window will appear on the monitor screen. Clicking on a Tab will not work, if the Tab's window has no information to display.

Searching Preliminaries

The FORMAE field in the above illustration will be the destination of all your search strings in CLCLT-4. Whenever you are searching any part of the CLCLT-4 library for a word, an expression, a phrase etc., you need to type it in the FORMAE field.

CLCLT-4 makes use of a robust search language to help you tell the program exactly what words and phrases you are looking for in a particular part of the library. This search language is rather complex and will take some getting used to. Here are the search characters you will need to know to compose productive searches:

  1. a blank space between words indicates that you want to find those words in that order.
  2. + (and)
  3. , (or)
  4. # (not)
  5. * (an unknown number of characters)
  6. ? (one unkown character)
  7. / (specifies a distance bewteen two forms)
  8. % (specifies an order of appearance as well as proximity between two forms)
  9. ( ) (functions as separators)

You can use these codes to ask CLCLT-4 to find the specific words and phrases that interest you in any work. Here are some sample search expressions using the characters listed above:

rogemus oremus
finds sentences containing these two words, but in this order.

finds sentences containing these two words.

finds sentences containing rogemus or oremus.

finds sentences containing rogemus but not oremus.

prae* finds forms beginning with prae-.
*atr* finds forms containing -atr-.
*ibus finds forms ending with -ibus.
*-g finds Greek words and characters.
N.B. You can use only two * in any single word.

dic?mus finds dicamus, dicimus, dicemus, etc.
A?mitt* finds words beginning with 'a' followed by another character, followed by -mitt- and a series on unknown characters.
N.B. Only one * can be used with the ? character.

daemonicae/4angelicae finds daemonicae and angelicae, or angelicae and daemonicae with a maximum of two words between them.
daemonicae%4angelicae works like the above example, but finds daemonicae and angelicae in that order.

Complex Searches

You can create complex and accurate searches using parentheses as separators especially when you are using more than two Boolean (and, or, not) codes. Your imagination is pretty much the limit; here is an example:

(interius, exterius) +atri*#(limen, domus)
This search asks CLCLT-4 to find all the sentences containing interius or exterius, and any sentences including some form of the word atrium, but not limen or domus.
N.B. Do not place the % and / characters next to parentheses.

The following search will fail:

Instead, form your search this way:
(carnaliter/4 spiraliter),(corporaliter/4 spiritaliter).

Using the CLCLT-4 Word Index

Now that you are familiar with the CLCLT-4 search language, what about words? You will often know what word(s) or phrases you are looking for and you will type them in to the FORMAE field to begin your search. But, if you are uncertain about the spelling of a word, or are looking for a specific declension or conjugation, or are even looking for lacunae? Use the CLCLT-4 index.

The index is basically a list of all the word forms found in all of the documents contained in the CLCLT-4 library. To access the index from the main search screen, click the mouse in the FORMAE field to position the cursor, then click on the FORMAE button. Scroll through the list using the mouse or type the first few letters of the word you are looking for to scroll directly to that word's forms. In this example the user has scrolled the index to the 'f' section:


Once you have found a word form you wish to use, click on it with the mouse and press the OK button to send it to the FORMAE field. Repeat this process to choose additional words. These will appear in the FORMAE field in the form x,y (where 'x' is the first word and 'y' the next; rememeber ',' means "or").
N.B. When you have chosen all the words you need, you can create whatever search expression you wish. Also, You can clear the entire Formae field at any time by pressing the ESC key.

Searching the Entire Database

If, for example, you wanted to trace the development and use of the word fabula through different historical periods, you could search the entire library of the CLCLT-4 database. Here's how: Use the mouse to click in the empty FORMAE field. Type fabul* or use the index to find all its forms.

Press ENTER to send your search to the database. CLCLT-4 will indicate the number of sentences (Sententiae) in which your search appears at the bottom right hand corner of the screen after it has searched the database for your search string.

Click the SENTENTIAE Tab to display the sentences.

You can scroll through the search results, select an entry by clicking on it with the mouse, and jump to the full text of that entry by clicking the TEXTUS Tab.If you like what you see, you can copy your search criteria, as well as all search results, to a disk for further use. Click on the floppy disk icon at the top of the screen to output to disk, or click on the printer icon to output to the printer.

N.B. CLCLT-4 will not save more than 40 sentences of continuous text per citation. This means that you cannot export an entire text of an author to a floppy disk.

When using CLCLT-4 in the LETRS facility, you must save your search results to the floppy drive otherwise you will lose all your data.

Searching using the filters

Searching levels of the CLCLT-4 library with the Auctor, Titulus, Clavis, and Aetas filters is just as easy. Before entering a search query in the FORMAE field, simply choose an author, work, Clavis number, or collection to search. Use the mouse to position the cursor in any filter field. When you start to look for an author or a work, you can type the information directly into the appropriate filter. But, as CLCLT-4 works with Latin names and titles, it is often best to choose a name or title from the contents lists of each field. To do this, position the cursor in the the desired field and press the labeled button next to that field. You will then see a list of all the CLCLT-4 contents for that field in the same format as the FORMAE index.

Select all the items you wish by clicking in the blank space to the left of the entry. Here's the FORMAE index again as an example, notice that the red checkmarks mark selected items. When you have selected all the desired items press ENTER to send it to your chosen field;

The ESC key will clear the entire field if you decide to start over. Press ENTER when you have finished. CLCLT-4 will display a screen listing all the chosen items marked with a check mark. You can use the Space-Bar to deselect/reselect any item if necessary - a useful function if you want to conduct additional searches on some but not all of your original choices. Confirm the list by clicking the OK button, then enter your search in the FORMAE field and you're off. Here's a summary of the 4 categories:

AUCTOR and TITULUS: Use these fields when you want to search the corpus of an author(s) (AUCTOR), or when you want to search a specific title(s). Please refer to the complete list of CLCLT-4 authors and titles for the contents of the CLCLT-4 library.

CLAVIS: Use this field if you know the specific code for an individual work you want to search. Otherwise, use the TITULUS field to find the work you need.

AETAS: Use this field to search entire specific collections. The designations for these collections are Aetas Patrum (CLCLT-4), Medii aevi scriptores (CLCLT-4), Concilia Oecumenic et Generalia Ecclesiae Catholicae (CLCLT-4), and Corpus Pseudepigraphorum latinorum Veteris Testamenti (CLCLT-4) respectively.

N.B.: Remember, after CLCLT-4 searches its library, it displays the number of passages containing your search string in the bottom right hand corner of the screen (lebeled Sententiae).
