Example of a quote lead -

New York Times

"Still Fragile, Haiti Makes Sales Pitch"

The writer used a quote lead to show the reaction of the business-elite upon seeing Haitian poverty, drawing in the reader through an almost juxtaposed image that is painted of the rich and poor separated only by the doors and windows of a vehicle. This lead is hard to follow until the story unfolds further down the page, but is still effective. The lead probably could be improved. A summary lead may not be the best fit as a substitute, however. A narrative lead might also accomplish the same objective as the quote lead that is given.

Example of a narrative lead -

New York Times

"Fight Nights and Reggae Pack Brazilian Churches"

The lead uses narrative and observation to gain interest from the reader, while not fully divulging all of the information. A nut graph follows the lead in the fifth paragraph to tie the narrative into the hard news. The lead seems to be the best fit for the story. Improvements don't seem necessary. A summary news lead would not be fitting for the story, as the environment depicted in the story appears to require more initial attention than the basic who, what, where, and when. A quote lead could also be effective if a solid quote was present.
