【 摘 要 】
The present paper aims to furnish simple proofs of some recent results about selections on product spaces obtained by Garc\'\i a-Ferreira, Miyazaki and Nogura. The topic is discussed in the framework of a result of Kat\v etov about complete normality of products. Also, some applications for products with a~ countably compact factor are demonstrated as well.
