My thoughts are, that there's a time and a place for "file slurp". :-)

In this case, to keep the logic simple, I'd loop over each input line, and
if it has the string "Authors:" at the start, I'd extract the name and
concatenate it to the variable "Authors: Name1; Name2; ...".

You may be getting some dubious gains in speed (although I haven't
checked), but IMHO you're obscuring the logic of a very simple task.
