Abstract
The off-shell structure of the string sigma model is investigated. In the open bosonic string, nonperturbative effects are shown to depend crucially on the regularization scheme. A scheme retaining the notion of string width reproduces the structure of Witten's string field theory and the associated unconventional gauge transformations.
