If you are like most MBA applicants, you'll probably have to prepare a draft recommendation letter for yourself. Not many supervisors/managers can find time to write detailed recos.

You need to see at least one recommendation letter to understand what does it actually mean. I couldn't find a single free sample reco letter on net that I could use and as far as books on this subject are concerned, this is the only one. So, you don't have much of a choice here.

But the good thing is in spite of being the only book about reco letters; this book is actually quite good. 30 sample letters will give you enough material to prepare detailed recos. Moreover, it's available as PDF, so you are spared the headaches of shipping and all that too.

The only reason I didn't give a 5 star to this book is because I couldn't find another book to compare it with. I'm sure the book could be improved further but even in its current version, it's of great value.
