Popis:	We present the results of the comparative analysis of the most known semi-empirical and empirical spectral atlases that was carried out using the data from the WBVR photometric catalogue. The results show that standard error of synthesized stellar magnitudes calculated with SEDs from best spectral atlases reaches 0.02 mag. It has been also found out that some of modern spectral atlases are burdened with significant systematic errors. The agreement for the 5000-10000 A spectral range is rather satisfactory, while there are problems for wavelengths shorter than 4400 A. Comment: 8 pages, 5 figures, this work was presented at the International Workshop on Stellar Spectral Libraries (IWSSL), Dehli, India, December 2011; Astronomical Society of India Conference Series (ASICS), P. Prugniel and H. P. Singh (Editors), 2012
