Why does this sentence have so many words to describe its title?


I’m translating _The Little Prince_ for fun and I have a question about the
first part of this sentence.

その本の名前は『ほんとう にあった話』というタイトルで、原始のジャングルについて書かれていた本だった

Why do we have so many naming words in this? We have 名前 and タイトル AND タイトル has
いう before it and I am confused.

Wouldn’t その本の名前は『ほんとう にあった話』 be enough?

I’ve just started learning Japanese so I know very little about its grammar
and structure. I've tried to find other sentences with 本の名前 and いうタイトル but I
can't find anything. It's either 本の名前 or 本のタイトル.




  * Using both 名前 and タイトル is indeed redundant. Strictly speaking, it should be either one of:

>     * その本は『ほんとうにあった話』というタイトルだった。
>     * その本の名前は『ほんとうにあった話』だった。

But I hesitate to call it a severe mistake. [Tautological
expressions](http://examples.yourdictionary.com/examples-of-tautology.html)
happen all the time both in English and Japanese. Also note that は is not a
subject marker but a topic marker. At first, は may seem "loose" or "illogical"
than English _be_. See
[this](https://japanese.stackexchange.com/a/48987/5010).

  * This という is grammatically mandatory to connect the actual title and the word タイトル. "A picture titled _Sunflower_ " is ヒマワリというタイトルの絵 in Japanese.
