Try changing split to split(/\b/), then change join(' ') to just join:
irb(main):001:0> material = 'Book "the Snowy Day," By Ezra Jack Keats'
=> "Book \"the Snowy Day,\" By Ezra Jack Keats"
irb(main):002:0> material.strip.split.map{ |w| w.capitalize }.join(' ')
=> "Book \"the Snowy Day,\" By Ezra Jack Keats"
irb(main):003:0> material.strip.split(/\b/).map{ |w| w.capitalize }.join
=> "Book \"The Snowy Day,\" By Ezra Jack Keats"
The split on /\b/ splits on word boundaries, preserving all the spaces
and punctuation between. That's why the join no longer needs spaces:
irb(main):004:0> material.strip.split(/\b/)
=> ["Book", " \"", "the", " ", "Snowy", " ", "Day", ",\" ", "By", " ",
"Ezra", " ", "Jack", " ", "Keats"]
