もう and けど in one sentence


How do もう and けど work in the bold sentence?

I think it means something like "but a little bit detailed book would be
better" but I'm not sure.

Also, I don't understand how もう works here. According to
[this](https://japanese.stackexchange.com/questions/530/how-can-i-
differentiate-between-%E3%82%82%E3%81%86-that-means-already-
and-%E3%82%82%E3%81%86-that-means-m) post もう has 2 meanings, and the one that
fits here is "additional". So, the sentence would be something like "but
additional a little detailed book would be better". To me it looks like the
customer was not satisfied with what the seller shown him, therefore he wanted
to get another book. Or did he want to buy 2 books (the one that the customer
offered and another one)?

Also, I would like to know whether けど is really a thing here and has to be
translated or not. As I read
[here](https://japanese.stackexchange.com/questions/28458/native-usage-
of-%E3%81%91%E3%81%A9), sometimes it can be used as a softener.

I think I get the general meaning of the sentence but I would like to know how
it works.

Yes, you are right. Since we are talking about books, "more
informative/detailed" might better suits with this situation.

> To me it looks like the customer was not satisfied with what the seller

Yes. Therefore he and shopper engaged in this conversation.

> ーもう少しくわしい本の方がいいんですけど。( I would rather like to purchase more informative (
> ore more detailed ) book, please.
>
> ーそうですか。それでは、こちらがいかがですか ( Alright, then, how about this one? )

I'n not sure what you try to mean by saying "a thing here." Here, けど/けれど is
working as a softer as you said, avoiding the decisive tone that might the
speaker offending to the shopper and telling the shopper your wishes ( I would
rather like to.. ) indirect way.

## Conclusion

> ーもう少しくわしい本の方がいいんですけど。

As I said,「もう」「けど」are working as 「More informative/detailed」, 「I would like
rather..., please」 than 「I want」respectively.

> ーもう少しくわしい本の方がいいんですけど。
>
> 「I would rather like to purchase more informative/detailed book, please」

Have a nice day.
