Quite an old paper, but some of the discussion on loops vs strings is still interesting.

The aim of the present paper is to discuss in some detail established results on the field.
In some strong sense, the review could be finished at once, because there are none. There
are, nevertheless, some interesting attempts, which look promising from certain points of
view. Perhaps the two approaches that have attracted more attention have been the loop
approach, on the one hand and strings on the other. We shall try to critically assess
prospects in both. Interesting related papers are [21][40].
