BALTIMORE – A presidential memorabilia collector who has acknowledged stealing thousands of rare and valuable documents from historical societies and archives nationwide was sentenced Wednesday to seven years in prison.

Barry Landau was caught stealing documents from the Maryland Historical Society in July 2011. An investigation concluded the 64-year-old New York City resident stole at least 6,500 items worth more than $1 million from archives around the country.

A number of the stolen documents are more than 100 years old and some are worth more than $100,000. They include copies of speeches President Franklin D. Roosevelt read from during his three inaugurations, a land grant signed by President Abraham Lincoln in 1861 and letters written by scientist Isaac Newton, Confederate Gen. Robert E. Lee and novelist Charles Dickens.
