As others have also pointed out, you cannot transparently 'inherit' one hash from another; but wouldn't

print $chapter{book}{name};

Be both acceptable and superior as its clear that it's the book's name, not the chapter's name, being printed

(Also, you could then use 'title' for both the title of the book and the title of the chapters if you wanted to):

#! perl -slw use strict; my %book = ( 'name' => 'abc', 'author' => 'monk', 'isbn' => '123-890', 'issn' => '@issn', ); my %chapter = ( 'book' => \%book, 'title' => 'xyz', 'page' => '90', ); print $chapter{book}{name}; __END__ C:\test>junk82 abc

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
