A series of almanacs of the Knowledge publishing house, published in 1964-1992. The forerunner of such collections were two books with which the publishing house conducted a kind of experiment: whether it is worth publishing science fiction or not. In 1963, the first two collections, "The New Signal" and "The Black Pillar," went out of print and received a positive readership. And in 1964, one of the longest series of Soviet science fiction was born.
