A handy reference book that is relatively (very relatively) easy to carry with you. You won't put it in your pocket or purse but it is small enough to keep with you most of the time. It is loaded with all of the really useful information you might need, specially if you're a nursing student. It doesn't take up a lot of space on your desk so you can keep it handy for those inevitable times that you come across a word or term you need to look up. Of course Google is handy when you're at home but being able to just grab this wee book and look up what ‘that’ word means is just so handy that I pick up this book first most of the time. And you can't beat the price!
