David raises an interesting question. I haven't yet got the new List of Lodges Masonic, but looking at the previous one I see that similarly it contained very few of the PHGLs.
Of course different GLs do have different recognition lists, and this is obviously a problem for the compilers of this book (which they acknowledge in their frontispiece) when they have to decide which GLs to include and which to leave out. For example, since I'm a UGLE member, I can visit most (although not all) of the PHGLs, whereas clearly GLTX members can't do that, whereas on the other hand there are some other GLs included in the book which you can visit but I can't (such as several in South and Central America which my GL doesn't recognise).
It'd be fascinating to see more details about exactly how the compilers take their decisions on what to include. However, I suspect that they won't tell us, because it'd probably just start a lot of arguments. As the compilers have previously pointed out, publishing separate editions (correctly reflecting the recognition list for each separate GL) would be very expensive.
T & F,
