In many textbooks, authors usually write about other people's research results without the type of detailed and extensive citations typically seen in a research paper.
Often times without any credit to the original researchers/authors.
In fact, the type of "neutral" tone used when authors talk about recent research areas makes it seems as if those areas have existed for hundreds of years.
For example, consider the sentence, "Xtacking is a type of 3D NAND with higher bit density and faster time-to-market." Xtacking was invented in 2018, and no authors is attributed.
I think this is more or less an accepted convention. And I understanding that having an excessive amount of citations will hinder readability.
However, I wonder what is the most acceptable way to credit the original authors when talking about results in a textbook context.
