| The data of the source first to deal with have to be entered onto a data sheet. The
differences of the second source has to be written into this form. The contents of
these sheets have to fed into the computer according to an established standard. The
computer adds the points of agreement of the first source to the divergent features of
the second one, and so a full-form is received again. For recording the next sources
the source most akin has to be used as a basis of comparison (printed out onto a new
data sheet). In such a way all the data of a chosen source can appear on the screen and
all we have to do is to enter the differences of the next source (i.e. 'to overwrite' the
comparative list). The work with the data sheets, computer and printer provides additional
opportunities for analysis, control and comparison as well as for evaluating the similarities
and differences. During this process the scholar feels urged to improve the data sheets, the
recordings and the programs. This empirical approach facilitates the choice of the appropriate
pairs of sources out of which the computer is supposed to compile comparative tables. |
