["Jeanne Drewes" <jdre@xxxxxxx>]

The Preservation Directorate of the Library of Congress announces the
27th lecture in its series on "Topics in Preservation Science (TOPS),"
Monday, April 23, 2007, from 10:00 am - 12:00 noon.  

Dr. Carl H. Haber, Senior Scientist in the Physics Division of Lawrence
Berkeley National Laboratory (LBNL) at the University of California,
will present *Imaging Methods for Recorded Sound and Preservation
Access: The I.R.E.N.E. Project and Future Prospects*.  

The Preservation Directorate has collaborated with LBNL to capture
sound from damaged phonographs and similar 2-D grooved recordings. The
prototype "I.R.E.N.E. Machine" has been installed at LC for fidelity
evaluation.  Future directions focus on developing a second device for
high-resolution  surface profiling of 3-D grooved media, such as wax
cylinders. 

Location:  Dining Room A, Madison Building 6th floor, Library of
Congress (101 Independence Avenue SE, Washington, D.C. 20540).

The Topics in Preservation Science lectures are free and open to the
