I've always thought it rather strange that the two English language websites devoted to J M Barrie (Anon, and this site) do not provide an exhaustive list of their subject's published works. Such a list is to be found, however, on this page of CĂ©line's French website: http://www.sirjmbarrie.com/bibliographie/bibliographie.htm
Similarly, it seems odd that none of these websites provides a list of all Barrie's works which are readable online (subject to the odd copyright issue here and there). Project Gutenberg has been referred to often as they offer the largest number of JMB's works, but some other of his works can be found elsewhere, notably on two other websites. Perhaps the following listings may be of use to some members - I've added one or two miscellaneous items:
