  The work described in this article is a continuation of the previously
initiated research on archival spectral observations carried out in the 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 are presented. The article is illustrated with
the possibilities of network access to the catalogues of observations taken
with various instruments in the interactive Aladin Sky Atlas with the
redirection to the original spectrograms. For this aim, the linear coordinates
of the scanned negatives were converted into a scale which 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 the
results of their independent processing with the data published for objects in
the "Izvestiya of the Crimean Astrophysical Observatory" journals.
