Entry-type for unpublished presentations

Which entry type you would use for unpublished presentations. I mean PowerPoint, latex-beamer and things like that. Most of the time they are available as PDF files.

Unpublished means it is not part of a proceeding or something like that. For example a presentation from a company intern education session or something like that. Kind of “private” or “draft”.

Well, that somehow depends on how often you deal with such entries - and whether you want to explicitly mark them as “unpublished presentations”.

If they are rather seldom I suggest to simply use the “Unpublished” standard entry type. If you frequently have to deal with such elements I would add a custom entry type.
