This quote provides a witty and somewhat cynical perspective on newspapers, comparing them to oversized books that are filled with advertisements and have a limited lifespan. It highlights the transient nature of newspapers, which are designed to deliver daily news but quickly become outdated as time progresses. The phrase "expiry date" cleverly conveys the idea that newspapers are perishable items, useful only for the moment they cover.

The mention of advertisements also touches on the commercial aspect of newspapers, reminding us that they are not purely informative objects but are also vehicles for consumerism and businesses seeking attention. In doing so, the quote invites us to think critically about the content we consume and the purpose behind it, questioning the balance between journalism and commercial interests.

Moreover, by likening a newspaper to a book, the quote acknowledges the substantial volume and variety of information that newspapers provide—ranging from news stories to editorials, features, and more. Yet, unlike books that can be treasured across time, newspapers are inherently ephemeral. This contrast between permanence and impermanence can lead us to reflect on how we value knowledge and how the format of information delivery shapes our relationship to it.

Overall, the quote encapsulates a clever observation that provokes thought about media consumption, the fleeting nature of daily news, and the underlying commercial realities tied to publishing.
