In the present-day cosmological standard,  the large scale structure of the Universe of woven of dark matter. This structure can be traced by observations of galaxies and AGN - however, only in a biased way, as properties of all extragalaxtic objects seem to depend on their location in the large scale structure. Moreover, this dependence evolves with cosmic time. In the last years new big reservoirs of data appear, among them multiwavelength data which are particularly well suited to study properties of a wide range of cosmic objects. The NEP field is a prominent and unique example of such data. On the other hand, new automated methods make studies of such samples easier - however, not without traps we need to try to avoid. In my talk, I will try to present and discuss the panorama emerging from recent studies. (TBA!)
