Paul Thompson's Complete 9/11 Timeline is an excellent resource. Browsing news entries frequently elicits thoughts of "isn’t that an amazing ‘coincidence’”, or “why didn't I ever hear about this before?”
There are effective ways to reference it. For example, individuals have their own entity tags, often with direct links to the news articles pertaining to them:
Other information is grouped in a more selective way and is available from the side of the website. For example:
With so much information, it is often helpful to quote relevant information from selected sources to make research articles.
Paul Thompson gives short excerpts of multiple and corroborating mainstream news articles with links to original sources for consultation. For example:
An employee at a gas station located across the street from the Pentagon servicing military personnel later says the station’s security cameras should have recorded the moment of impact. However, he says, “I’ve never seen what the pictures looked like. The FBI was here within minutes and took the film.” [Richmond Times-Dispatch, 12/11/2001] A security camera atop a hotel close to the Pentagon also records the impact. Hotel employees watch the film several times before the FBI confiscates the video. [Washington Times, 9/21/2001] The Justice Department will refuse to release the footage, claiming that if they did it might provide intelligence to someone who would want to harm the US, but some Pentagon officials say they see no national security value to the video. [CNN, 3/7/2002] The gas station footage and video taken from one nearby hotel, the Doubletree, will eventually be released in 2006, but do not show much (see September 13, 2006-Early December 2006). Reporter Sandra Jontz, who is evacuated from the Pentagon some time after it is hit, notices a Department of Transportation camera that monitors traffic backups pointed towards the crash site. [Bull and Erman, 2002, pp. 281] As of the end of 2006, the footage from this camera has not been released.
While the site is excellent, and I highly recommend it for 9/11 researchers, I do not use the search engine on the site because I find it to be unreliable. Instead I use Google:
This method usually provides much more reliable results and can be used to find information that you are looking for.
