STYLE-919, STYLE-920, STYLE-921, STYLE-922, STYLE-923 are all Japanese sites, all seem legit and ok to add. Most should be available for artists and works, one (STYLE-921) only for works.
STYLE-763 is a Dutch site for bible texts - they all seem to be out of copyright. Works only.
STYLE-798 is a site for out of copyright Nordic texts (including specific poems, such as http://runeberg.org/kacpoet/0023.html). Works only.
