This is, as the title indicates, principally a reference book and not something one would normally use to learn a language. If you are brave, however, and unafraid of grammar and piles of language data, Portuguese: A Reference Manual by Sheila Ackerlind and Rebecca Jones-Kellogg may be the perfect book for you.
It comes across as reliable, conscientious, and exceedingly thorough. Good for chart- and list-friendly types. Not good for people who like some handholding in their language-learning.
Portuguese: A Reference Manual offers useful comparisons between Spanish and Portuguese!
