The paper presents a survey of profiles of reasonably strong diffuse interstellar bands (DIBs) based on the extensive set of high‐resolution spectra acquired with the aid of echelle spectrographs installed at the 2‐m Terskol, 2‐m Pic du Midi and 1‐m SAO telescopes. The surveyed diffuse interstellar bands cover the spectral ranges of blue and near‐infrared, i.e the DIBs not surveyed by Krełowski & Schmidt. The possible modifications caused by stellar and telluric lines are discussed. The very broad features such as 4430 are not discussed because the shapes of their profiles, extracted from echelle spectra, are very uncertain. The signal‐to‐noise (S/N) ratios of the spectra are not high enough to enable discussion of the profiles of numerous weak interstellar features discovered recently.
