With there being five big publishing houses and about a billion imprints underneath each of them how can we possibly keep up with all the books being produced?

As the title says there are five big Publishing houses with a huge amount of imprints underneath each producing so many books that isn’t funny. This means a massive majority of these books are going to go unnoticed undiscovered with hardly anyone if at all talking about them on the Internet. Now I would like to discover these books for myself and I’m hoping you guys could help me.

Is there any specific websites that happened to have a catalog of sorts with each book and their cover that the polishing house has put out from the moment they started up until now? I mean the other day I came across a website that had exactly what I needed but I can’t recall the name and how I found it. Not only that but it only had books from one specific imprint and I don’t even no if all the books that I saw listed on there was everything that had ever published or just a select few.
