Lecture on preservation science

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 10am - 12 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".

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

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.

The Topics in Preservation Science lectures are free and open to the
public. For more information about this series, which is continually
expanded and updated, see
