The 700 series, also called Psi, was published by the Kyiv publishing house Nika Center in 1994-2007. It included books by both famous and little-known authors with a mystical connotation. Many books were published in Russian for the first time. Of particular note is the quality of the publication - small volumes with elegant vignettes and a golden letter "psi" on the cover. The distribution includes ALL books in the series: 7 were scanned by me, the rest were found on the network.
