From: "geert hoogeveen" From this file it is obvious that this system has become very redundant. Some publications have 10 entries in this file. At least in this way it can be seen which are the different references for the same publication. It prevents the lookup of the same publication again. I have used some simplifications: more than three author names was replaced by et al, because the purpose of this file is to find a publication, not to find an author. And all the no/nr/nrs/issue/facs/vol/heft indications were replaced by a simple N. If anyone has questions about this, I suggest to send them offlist to me.
