## Summary {#summary} [O'Reilly Media](https://en.wikipedia.org/wiki/O%27Reilly_Media) is a book publisher/learning company similar to [Packt Publishing]({{< relref "packt.md" >}}) known for its distinctive animal covers. Quality feels like it's been lapsing recently, but I think it's more of a industry-wide thing. Still, some of the books under their banner are still widely recommended. For example, [Martin Kleppmann :: Designing Data-Intensive Applications: The Big Ideas Behind Reliable, Scalable, and Maintainable Systems]({{< relref "../references/martinkleppmannDesigningDataIntensiveApplications2017.md" >}}) is a book I still see praised in tech circles.
