We consider the spatial clustering of massive black hole (MBH) mergers, anddiscuss possible ways to use gravitational wave observations in the LISA andDECIGO/BBO range for obtaining cosmological and cosmogonical information.Constraints on large scale structure (LSS) and merger histories may be possibleby detections of an alignment of the GW polarization direction with principalaxes of the LSS. Constraints on the merger physics and the reionization epochmay be obtained by GW measurements of MBH correlation lengths, in the case whenthe MBH angular momentum loss occurs through gas drag. Such measurements wouldprovide information about the LSS and the reionization epoch, additional to andindependent of any obtained from electromagnetic signals, as well as about theastrophysics of MBH mergers.Comment: 14 pages, 3 figures, accepted for publication in Ap
