The Library of Congress does not have legal authority to perform
preservation treatments on materials owned by other institutions
or individuals. The Preservation Directorate however, maintains
a strong outreach program and provides information to other government
agencies, libraries and the general public.
Any preservation procedures described within our publications
or website have been used by the Library of Congress and are considered
suitable by the Library as described; however, the Library will
not be responsible for damage to privately-held collections should
damage result from the use of these procedures.
To find a conservator to treat damaged books and other valuable
materials, consult the Guidelines for Selecting a Conservator of the American Institute for Conservation
of Historic and Artistic Works (AIC).
Professional book appraisers
and most book sellers will appraise and evaluate book materials. The Antiquarian Booksellers Association
of America (ABAA) maintains an online
membership directory with addresses, phone numbers and area
specialties such as early printed books or art and music.
