The Changing Look AGNs (CL AGNs) are objects that undergo dramatic variability of the emission line profiles and classification type of which can move from one spectral class to another within a very short time interval (from days to years). We started the project of spectral and photometric multiwave- lengths (from IR to X-ray) monitoring which includes the selected set of the CL AGNs. At start we were going to use several telescopes: 2-m (ShAO), 2.5-m, 1.25-m, 0.6-m, 0.5-m (SAI), MASTER global net, and Swift (UVOT and XRT) observatories. Then additionally, we used spectral data obtained at the WIRO, SAAO and photometry obtained at the WISE, and some other observatories. The main goal of the project is to investigate the possibilities for the repeating CL events. Investigation of such type of objects can be very informative for understanding the nature of these fast strong variations as well as the physics of the AGNs. We present the first results of our research for several CL AGNs which were mostly published already. We discovered some new CL events in several objects and discussed common properties of the CL AGNs
