view it, and for years even the kinds of people, with a preference for students and working class. Visitors still must make appointments in advance to see the collection, and only a limited number are allowed in the galleries at one time. In the mid-20th century, local government restricted traffic to the current campus, located in a residential neighborhood located at 300 North Latch's Lane, Merion, Pennsylvania. Barnes' constraints, local factors, and management issues pushed the Foundation near bankruptcy by the 1990s. Supporters began to explore plans to move the collection to a more public location and maintain it to museum standards. To raise money for needed renovations to the main building to protect the collection, the Foundation sent some of the most famous Impressionist and Modern paintings on tour. In 2002, the Attorney General of Pennsylvania D. Michael Fisher contested Albert C. Barnes' will, arguing that the Merion location of the collection and small number of board members limited the Foundation's ability to sustain itself financially. Pennsylvania Governor Edward Rendell brokered a settlement in 2005 between the Barnes Foundation and Lincoln University. This agreement resulted in the number of directors increasing. This has diluted Lincoln's influence over the collection, now valued at approximately twenty-five billion dollars. A documentary named The Art of the Steal depicts the events.
