Abstract: (Abridged) We present the results of the photometric and spectroscopic identification of 110 hard X-ray selected sources (6e-15 1000, while their Lx, L(R) and Nh are similar. This suggests that while the central engine of narrow-line AGNs and XBONGs looks similar, the narrow-line region in XBONGs could be strongly inhibited or obscured.<br />Comment: Accepted for publication in A&A, 18 pages, 19 figures
