review text: The best linear methods of approximation in some classes of analytic functions whose growth is regulated by that of their derivative's second circular variation in integral norm are found. All the latter classes are subspaces of Hardy spaces of analytic functions. The results of the paper extend those of \textit{L. V. Taikov} [Mat. Zametki 22, 285-295 (1977; Zbl 0382.30026)].
