Hi Anne

If the only problem you are tackling is breaking lines between isbn and 
following number, then surely a simple substitute will suffice?

echo 'isbn 23987
isbn 293487
' |perl -p0e's/isbn\s*[\x0d\x0a]*\s*(\d+)/isbn $1/gs'
isbn 23987
isbn 98777
isbn 239487
isbn 293487

(to be adjusted according to relevant line feed carriage return situation)
