Thus, the costs per copy decrease hyperbolically with the print run, as is
shown in figure 3. Here we see that publishing a scientific book may become
cheaper by the factor three when raising the print run from 1,000 to 4,000.
Due to hyperbolic feature, a further raise of the print run does not anymore
reduce the production costs so striking.

Table 2
Likewise, the costs for publishing a scientific periodical depend on the print
run. Table 2 is added providing information on the print run of some profes-
sional journals of our field. However, some more factors have an impact on the
costs of periodicals. More specific, the volume of advertisement, depending in
itself on the print run, can reduce costs considerably. Therefore, we are not too
much surprised judging from table 3 that costs of two well known journals differ
by a. factor .of. ten.

Table 3
Coming to the present state of biliography in our broad field we find that some
countries, such as both Germanies, the Netherlands, Hungary and England, compile
literature references being published monthly in the format of cards or book-
lets. In addition, some individuals publish occasionally lists of literature re-
ferences covering their narrow fields. Though valuable these attempts are, the
outcome is not very practicable, for it is a tedious undertaking to use them.
The main disadvantage is that combination of serveral keywords within a litera-
ture search is most time consuming. Electronic data processing seems to be the
. remedy. That requires storage of all information into a data base. Other orga-
nizations such as NASA and Lockheed have already arranged their data bases with
some millions of literature references inlcuding Occasionally also some sub-
fields of remote sensing. However, for our broad field no reliable data basis
is available in no country.
