As a method of choosing books, Akinori Takada introduce a technique called 棚見(Tanami, shelf-viewing).

❶: Look all the books on the shelves in the field (see the table of contents if there is some book you are interested)

❷: Repeat ❶ above in multiple book stores if possible

❸: Sketch the whole picture of the field

A shelf is a collection of books. Akinori Takada focuses on a collection of books before reading a specific book. He uses a large amount of time on shelf-viewing.

He also says, "Many of us are accustomed to learning in order from easy book to difficult book in junior high school education, but you should choose books of your interest here, not an easy book." Choosing by your interests is to keep you motivated.
