Protesters marked Thanksgiving with a feast for 5,000 people in Lower Manhattan's Zuccotti Park, the site where their encampment once stood.

A volunteer with the demonstrators' public relations group said they had meals and music for 5,000 people.

The food was donated by restaurants and individual supporters.

Music was set to be acoustic, because protesters do not have a permit for loudspeakers.

A canned food drive was also held, with donations going to local food banks and pantries.

Police Commissioner Issues Warning On Media Interference

Police officers are being ordered to back off the media after several journalists were arrested at Zuccotti Park.

In a letter to station houses, Police Commissioner Ray Kelly says officers should not unreasonably interfere with media access during the Occupy Wall Street protests.

He says those who do not follow the rule will face disciplinary action.

The police department came under fire for arresting several journalists and blocking others from gaining access to the park when it was being cleaned out.

Dispute Over Books Continues

Meanwhile, Occupy Wall Street protesters say the city's raid of Zuccotti Park destroyed, damaged or lost more than 3,000 books.

They presented some of the roughly 1,200 books recovered from the Department of Sanitation but said two thirds of their collection cannot be found at the facility.

Demonstrators say last week's raid left them no time to save the 4,000 books in the "people's library," which were donated from the start of the occupation and then catalogued in Zuccotti Park.

They want an apology and a promise from Mayor Michael Bloomberg that it won't happen again.

They also want the collection replaced.

"To go to the sanitation facility and to see how heartlessly and callously all of our work, all of the people's work has been thrown out like so much garbage is heartbreaking," said one protester.

The mayor's office responded by saying, “The protestors were given ample opportunity take their possessions with them... The City is making an extraordinary effort to make sure all property left behind is available to be retrieved... In fact, the City has made arrangements for the property to be available for pickup for the next 90 days.”
