Crawl of outlinks from wikipedia.org started March, 2016. These files are currently not publicly accessible. Properties of this collection. It has been several years since the last time we did this. For this collection, several things were done: 1. Turned off duplicate detection. This collection will be complete, as there is a good chance we will share the data, and sharing data with pointers to random other collections, is a complex problem. 2. For the first time, did all the different wikis. The original runs were just against the enwiki. This one, the seed list was built from all 865 collections. ||||| 6 years ago 
 
 (CNN) - A new book, now number six on the New York Times' Best Sellers list, is putting the so-called "birther" issue back on the national stage. 
 
 "Where's the Birth Certificate?" by Jerome Corsi, which debuted on the list out Sunday, argues President Obama is not a natural-born U.S. citizen and therefore cannot be president. 
 
 
 
 "Corsi demonstrates conclusively that no legal authority has ever verified Obama's legal eligibility to be president," the book reads. 
 
 Corsi also wrote "The Obama Nation" and "Unfit for Command," a 2004 book about Sen. John Kerry that focused on the "Swift Boat" television ads. 
 
 The "birther" controversy was front-and-center earlier this year, as billionaire businessman and real estate mogul Donald Trump repeatedly discussed the issue while considering a run for the White House. President Obama ultimately released the long-form version of his birth certificate that shows he was born in Hawaii on August 4, 1961. Soon after, Trump announced he would not make a bid for the GOP presidential nomination. 
 
 Despite the president's actions, 17 percent of Americans think the president was definitely or probably not born in the U.S., according to a recent CNN/Opinion Research Corporation poll taken after the president's announcement. 
 
 The survey showed a drop from the March poll numbers when 25 percent of those surveyed said the president was definitely or probably not born in America.
– We’ve seen the long form certificate, but the birther issue just won’t die. Author Jerome Corsi’s new book Where’s the Birth Certificate? debuts at number six on the New York Times’ Best Sellers list out Sunday, according to CNN. The book argues that President Obama’s citizenship has never been verified by a legal authority. Despite the White House release of the president's Certificate of Live Birth, 17% of Americans think he was definitely or probably not born in the US, according to a recent poll taken after Obama's birth certificate announcement.
