BothUM1974 & UM2179 have exactly the same title:

So how are we supposed to distinguish the two - without having to open both ?

These documents refer to different set of nucle-144 boards.

When you select a 144 pin boards here:

you will see the particular version of the nucle0-144 document for particular board:

I think Andrew's point is that it needs to be more obvious from the outside.

The divergence has started with the availability of Ethernet, and now the L4(+) parts.

I simply described how I use these documents.

I started from selecting a board so it was not misleading to me as only one document is shown on the particular board page.

Maybe the ST also assumed that we start from selecting a board.

IMO it's not the naming of documents flawed, but the naming of boards.

They are different (or populated differently) thus they should have distinct names - and then the names of the documents would follow that.

Yes - presumably there is some key difference between the 'Nucleo 144' boards covered in one, and the 

'Nucleo 144' boards covered in the other - so that should be reflected in both the board names and the corresponding document titles.

Rather like there is  the 'Nucleo 64' seriews, and the 'Nucleo 64-P' series - each with its own appropriately-titled User Manual.

(Although ISTR I couldn't find any clear definition of the difference between the 64 and 64-P,  without having to trawl through the 2 User Manuals - but that's another story.)
