copyright

This is a question about copyright laws.  I have a book from the library which is copyrighted 1942 saying, all rights reserved, This book, or parts thereof must not be reproduced in any form without permission.  So if the book is copyrighted in 1942, is it still copyrighted, or has the copyright expired by now, 68 years later.  There are some prints of water colors in the book I would like to share. 

Isaac Wardle Questions

As I have been writing Isaac's history, I have some questions.  If you have answers and sources please let me know.

Is there documentation of Isaac chopping the trees at the Cove, or is this based on passed down family conversation only.  I have the one-page history Isaac wrote, but it does not mention this.

Did Isaac's father give him an ax to take on the journey with him?  I thought I was told this, but can't find it written any place.

Does anyone know what came of Joseph Wardle, Isaac's next younger brother?  Did he pass away before the family (Parents and James) crossed the plains in 1860.

Same goes for Hannah Wardle.  Does anyone know what came of she and her husband, Frederick Udy?  It is understood they went to Australia but is there any documentation?
