It is a wonderful idea to make available recordings of great speeches. I hope we have more of this in the future.
In the case of older speeches, the selection is very good, considering the restraints of time, and the readers are uniformly excellent.
As for the modern speeches, it is a marvel of technology that we can hear these speeches as delivered. It is incredible that we can hear the voice of William Jennings Bryan. I can listen to Martin Luther King's "I have a dream" a thousand times and never tire of it! How I wish I could listen to the voice of Patrick Henry! But this selection is too heavily weighted to the modern, and many of those do not deserve billing as the GREATEST speeches of ALL TIME. Also, some of the modern speeches which are included are abridged, e.g. Reagan is cut off in the middle of a sentence, while lengthy and undeserving speeches are played out in their entirety.
Also, with only a few exceptions, the selection is almost entirely American. It is hard to understand why Jimmy Carter's lengthy speech on energy policy is included, while Pericles' funeral oration is not; or why only a small portion of a single Winston Churchill speech is included; why while Bill Clinton's complete 1993 pulpit address, in excess of 20 minutes, is included.
It would be helpful if the complete list of speeches were available to online buyers, as it would be to shoppers in a brick and mortar store.

I have listened to this collection twice now, both times with pleasure. Hearing the acutal voices of Amelia Earhart, Rev. Martin Luther King, Winston Churchill and Neil Armstrong made a deeper connection than simply reading their words. The collection showcases different subjects and many times contrasts opposing viewpoints of the ideas. This volume is a fantastic introduction to the moving ideals and sometimes sad truths that have influenced Western Civilization.
