Bibus Bibliographic software

Hello, First of all, sorry for my bad english (i'm french) My problem concern the referencing of author's chapiter name which differes from the name(s) of author's book. "chapiter" or "part of the book" class of referencing don't offer the mean to do that. I just have the choice to put author's book name. Do i have to creat custom renferencing class or do i missed something ? Please help

In science, the book author is the Editor. You thus have 2 authors if you choose "Book Chapter": "Editor" => book author "Author" => Chapter author

Both can be formated independently ibn the Style editor

All the best, Pierre
