@LadyDestiny I feel you - its one of my favorite lorebooks too!

As far as I know its not a lorebook that is available as a real decor, since its part of the eidetic memory library and I don't think it has been added separately.

But... if you are on PC, you can add it via the Essential Housing Tools addon. You basically just insert one of the library FX - the one that pulls specific titles from the eidetic memory library - and set it to "Summerset Scrolls," "Words of the Fallen". After that, whenever you are outside of edit mode, if your cursor passes over the book, it will call up a prompt to read the lorebook if you interact with it, and then it just opens the lore entry on your screen so you can read it. You can even hide the FX inside an actual book decor, or scroll decor, or a bookshelf, and your cursor will still call it up when you pass over the place you hid it.

Click here for a link to the forum post where Cardi first announced the library feature in case you want more information/pictures and examples - note the initial library FX did not include the ability to call up specific texts - that was added later and I believe is discussed further down in the thread.
