| Problem Area | Description | |--------------|-------------| | | Search engines confuse “V. Govorov” (one co-author) with the whole team; no solo “V. Govorov” book exists. | | Copyright status | Mir Publishers (defunct) and Nauka hold copyright; digital copies are not legally distributed for free. English edition is still under copyright (life of author + 70 years). | | Availability | No legal PDF on Springer, Amazon, Google Books, or open access repositories. Out-of-print since ~1990. | | Language confusion | Russian PDFs of «Задачи по математике» (Govorov et al.) exist on Russian trackers, but English version is scarce. | | Scan quality | Available scans (often from library copies) are poor: missing pages, illegible equations, no OCR. | | Confusion with other authors | Other Soviet problem books (e.g., by Lidsky, Telyakovsky, or Dorofeev) are sometimes mislabeled “Govorov.” |
