そうはいっても、5600頁ある文書を、一回読んで理解できるとも思えない。

過去からの技術の積み重ねで、多重構造になっているかもしれない。

 <この項は書きかけです。順次追記します。>
# 方法
これまでに、いっくつかの方法を取ってきた。

## 単語帳(word count)
文書に出てくるすべての単語を洗い出し、予め単語帳を作っておけば、知らない単語が出てくるということはなくなる。

## 目次(content)
目次を知れば、全体の文書構造がわかる。目次に出ている単語だけから出発する方法もある。

## 参考文献(reference)
本文だけでなく、参考文献すべてをあたってあれば、内容がわからないことにはならない。

## 短縮名(sort name)
単語帳があっても、短縮名の意味を知らなければ読めない。

今回は、短縮名から確認してみる。

# 目次
８つの節(SECTION)に別れている。
編集の都合だろうと推測。章節番号は連続している。、頁番号は、各節目次が長く、Introductionが５５頁から始まっている。
