La Ondo de Esperanto
La Ondo de Esperanto (English: The Wave of Esperanto) was an illustrated Esperanto periodical published monthly in the Russian Baltic Sea enclave of Kaliningrad (formerly Königsberg). Since 2017 it has been available only as an online magazine in PDF or EPUB formats.
The publication inherits its name from a magazine of the same title published from 1909 to 1921 by Aleksandr Saĥarov. Since its revival in 1991, more than 300 issues have been produced. Each issue has about 20 to 30 articles — some brief, others lengthy — on Esperantist activities throughout the world. A free literary supplement was bound into each year's December issue. Issues are typically 24 pages in A4 format, with numerous pictures and illustrations.
