DYABOLA - Manual of Subject Catalogues
2.1 Searching Under Subject Headings (=Subject)

An example will illustrate how a literature search is carried out with the help of assigned Subject Headings(= Subjects). We are looking for literature on

Roman aqueducts.

Quit (if necessary) the Quick Search Menu by using the ESC-Key. In the Search Option Menu we can use the Directional key to select the "Subject" option and confirm by pressing Return.

The top level of the hierarchic Subject Matter system is now displayed:

001* PraxInst   practice and institutions 002* Slbd   collected works 004* Pers   personalia, ... 005* MusSlg museums and collections 007* Top   topography 008* TM   technology and material 009* Anthr   anthropology 010* Kg   history of art 011* Archit architecture 012* Plast   plastic art and sculpture 015* Portr   protrait

Here, using the Arrow (directional) and Return keys, we again select the heading "Architecture". An asterisk (*) indicates that at this point the term is further sub-divided. After we have pressed Return a further list subordinate to the term "Architecture" is displayed:

001* Kg   history of art 002* Mon   monuments 007* Baugl architectural members ...

Here we naturally choose "Monuments" and press Return to move to the next level, which lists the various types of monuments:

004 Aedic   aediculae, naiskoi and tetrastyla 008 Altäre   altars (built) 012 Amphit   amphitheatres 016 Aquäd aqueducts 020 Bäder   baths 024 Basen   bases 028 . . .   basilicas

Again we move the cursor to the desired term, i.e. "Aqueducts". Now we have adequately specified criteria for the search. Using the key combination SHIFT + RETURN we confirm that we want to search under this Subject. The Subject Heading lists now disappear and the program asks you in a small window what name you want to give to the expected Search Result. The name can be up to eight characters long and should be for-mulated to avoid any misunderstanding. In our case it would make sense to enter "aqueduct".
