For the bright southern Be star mu Cen, we publish all spectra that have been used in the previous papers of this series. An overview of the data is given and the published results obtained with these data are summarized. All data have been obtained from La Silla. In detail, these are 28 spectra taken with Flash at the ESO 50-cm (400 nm to 670 nm), 426 blue and 443 red spectra taken with Heros using the ESO 50-cm and the ESO 1.52-m (350 nm to 860 nm), 47 spectra taken with Feros at the ESO 1.5-m (370 nm to 920 nm), 2 x 348 spectra taken with the Boller and Chivens at the ESO 1.52-m (345 nm to 510 nm), and 310 spectra of He I 6678 and 27 spectra of Si III 4553 taken with the CAT/CES. mu Cen was found to be a multiperiodic non-radially pulsating star, with indications for a coupling between the multiperiodic beating and the star-to-disk mass transfer.
