’s James A. Martin reviews GetAbstract, an app that provides brief summaries of business books. GetAbstract’s website “provides downloadable summaries of more than 10,000 business books, TED Talks and other content, organized in 12 categories and with 50 new summaries added each month….You can download the apps for iOS, Android, Windows Phone, andBlackBerry devices. They are free, and you can use them to download up to six free summaries as part of a trial. After that, you need a subscription, which range from $89 a year to $999 a year.”

Mr. Martin’s only complaint is that many current best sellers are not offered.
