I'm always reluctant to have list Q/A, simply because there are so many resources. Curation of such a list needs to be done (a) regularly in case links expire and/or new resources are available, and (b) by a dedicated subject matter expert. In an artistic field, this becomes even trickier because the potential for different opinions about "best" technique and "best" results may vary widely, as well as different artists having unique approaches and backgrounds (and therefore perhaps no knowledge of a really ideal book for beginners). There is also a technical challenge of community wikis, in that new users don't always use them properly and sometimes add an answer instead of editing the wiki. It can rapidly become disorganized.
Worse, A&C has a broader scope than many other StackExchange sites. This is by design, and isn't bad, until we try to look at compiling a "best resources" list. Even if we limit the scope from "all arts & crafts)...
Arts (& Crafts)
----> Painting (and Drawing and Sculpting...)
----> Oil paints (and acrylic and watercolor...)
----> Landscapes (and portraits and still life...)
Between tutorials, websites, and books, there are probably a long list of resources available just for landscapes using oil paint. Therefore the list of possible lists is fairly long, only multiplying the complexity of organizing and maintaining such a reference library.
Perhaps a different approach would be asking whether a given book is a good resource before deciding to buy it.
I am considering purchasing Oil Landscapes For Newbies by Some Painter. Since it's expensive, I wanted to know what techniques it covers and whether I'll really learn what I want from it...
