The work described in this article is a continuation of the previously initiated research on archival spectral observations carried out in Crimea. It covers a time interval of about 90 years and contains information about spectroscopy using various facilities: from the wide-angle astrographs with an objective prism to the main CrAO telescope - ZTSh. A brief history of telescopes and their equipment is presented. The article is illustrated with possibilities of a network access to the catalogues of observations taken with various instruments in the interactive Aladin Sky Atlas with the redirection to original spectrograms. To this aim, the linear coordinates of scanned negatives were converted into a scale that corresponds to the wavelengths. The possibilities of taking into account the spectral sensitivity of the recorded images by the absolute energy distribution are shown. A feature of this work is the connection of digitized original observations and results of their independent processing with data published for objects in the Izvestiya Krymskoi Astrofizicheskoi Observatorii
