I shared a screenshot of a PDF on my phone, a map of the Milky Way Galaxy from a PDF copy of the Star Trek Star Fleet Technical Manual. (I leave my physical copy, from the 1986 printing, at home.)

Much in this book has since been superseded. In particular, the map of the Federation's exploration zone is far too large even by the book's own terms, given that the warp speeds described are too slow to reach the sphere's edges.
