Binh Nhu Ngo$29.95 $27.55
Very good, very affordable textbook for self-teaching Vietnamese. Highly recommended.
Phan Van Giuong$19.95 $18.35
Pretty good Vietnamese to English and English to Vietnamese dictionary that won't break your fingers! I use it a lot, and it's noticeably very geared towards traveling for business and pleasure in Vietnam. Do you want to know how to say "emolument" in Vietnamese? This is your dictionary. Also just for a lot of everyday stuff.
Andre Nguyen Van Chau$102.00
This is a very complete, very huge, very heavy dictionary that is a requirement if you're a dedicated English-speaking student of Vietnamese. It's got a lot of terms involving multiple areas of study (especially science), and also it's very unwieldy. But extremely valuable.
Nhien D Nguyen$17.95 $16.51
A great little book to practice reading Vietnamese, especially if you love cats like I do. The poems are in both Vietnamese and English, and you soon learn the differences in how these two languages express the same concepts. Often it's very different, and that helps you get into the mindset for each language that is best for understanding.
