You get a List containing the text of all lines in the fold:

Then you find the offsets in that list of the matching lines:
> let matchlinea = match(line, '^\s*author.*{.*}.*') + 1
> let matchlinet = match(line, '^\s*title.*{.*}.*') + 1
Then you use those offsets as line numbers, instead of offsets into a
list. Why are you using getline(match()+1) here, instead of
line[match()] ?

Seems to me that those lines should be:
let matchlinea = match(line, '^\s*author.*{.*}.*')
let matchlinet = match(line, '^\s*title.*{.*}.*')
let matcha = substitute(line[matchlinea], '^.*{\(.*\)}*.*$', '\1', 'g')
let matcht = substitute(line[matchlinet], '^.*{\(.*\)}*.*$', '\1', 'g')

Try that, see if it helps.
