In order to save storage capacity the titles of journals and other periodicals are only stored as code numbers. A further advantage is that the journal titles are always abbreviated in an unambiguous way. For the display and printout the MOGADOC-specific code numbers are converted into the titles by means of a dictionary. On the other hand the code numbers also enable convenient searches of specific journals.

In the list (download here) journals and periodicals are given, which are screened for the data compilation. Hereby cross references between the translation and the original journal are also given. However, in a few cases the original journals and the English translation journals are combined under a new code number.
