A scientist writes a multi-volume monograph reflecting his latest research results.
In the first volume a certain topic is presented but incompletely because at the time of writing the research on this topic was partial.
In the second volume, more research on the topic is presented and the researcher wants to present the topic systematically. Because of this the researcher wants to repeat information that is already contained in the first volume (otherwise it cannot be presented systematically enough). This amounts to about 8 % of the pages of the first volume.
Question: What response does the researcher have to expect from book editors for duplicating information on the topic which was already published in the first volume?
