Abstract: The very first spectrograms of 39 seyfert galaxies are demonstrated. All these objects were taken from the Markarian's lists of galaxies. They were firstly investigated and classified at Fesenkov Astrophysical Institute within 1973-1988. Spectral study was carried out with a slit spectrograph, attached to the 70-cm telescope and equipped with a three cascades image-tube. Repeated observations of 22 galaxies were derived in 1985-2000. An analysis of a possible spectral variability of studied galaxies over 10-26 years was made. A list of objects, which are the most interesting for the further observations is presented.
