An Essential
Format: Paperback
I've created PowerPoints for executives in major corporations and national non-profits for years now, and this is one of the first books I suggest anyone who needs to create their own PowerPoint look to. Beyond Bullet points is accessable enough that the novice PowerPoint user can understand what's going on and use the lessons in his or her next presentation; it's also detailed and challenging enough that even an old salt like me can find things to learn and do. Don't be another person who stands on stage reading their PowerPoint, and don't let reading your slides distract the audience from your presentation; follow the suggestions in this book and wow your audience.

Bad book for SOA exam, but oh well.
Format: Paperback
While required by Society of Actuaries as the textbook for Short Term Actuarial Models exam, I could not recommend this textbook for any other purposes. Written by two Canadian actuaries, a lot of terms and explanations used in this textbook cannot be transferred into US P&C insurance.
It fails to explains insurance's purpose and products effectively and as an intro book with unnecessary sentences to deliver personal thoughts.
It is also a mess in following sections on ratemaking and reserving. I cannot sense a flow from this book that guides readers in an approachable manner.
Overall, author compromises the size AND the quality.
