General Writing and Grammar Help/Library of Congress Catalog Card Number


Dear Ted,  

Can you please help me to understand the "Library of Congress Catalog Card Number"

For example, I have a book that states the following:

Library of Congress Catalog Card Number:  70-123926

Does this mean that this book was published in 1970?

Is there any significance to the "123926" part of this Catalog Card Number?

Thank you!!



Dear Rich:

70-123926 is the CONTROL number for the book.  In short, it was book #123926 that the Library of Congress received in 1970.

It is NOT the "catalog number."
