PDF and DjVu formats
[edit]Although PDF and DjVu file formats are permitted, they are expected to be used only in appropriate cases. There should be some reason for the choice of format that is in line with Commons' aims. All of the above rules apply as well, of course.
An admin considering whether to delete a PDF or DjVu file may have to exercise judgement as to whether the chosen format is in line with Commons' aims, and the context and intent (if known) may be relevant. For example, while a published university thesis in PDF format may be OK, a user-created original-research article that is making use of Commons as a free web-host may not be.
Files that might realistically be useful to one or more other Wikimedia projects, e.g. Wikisource or Wikibooks, should be kept; deletions should not be based on the sole ground that the file would be better hosted on one of those other projects. Any media file that is realistically useful to or is within the scope of even one other Wikimedia Foundation project can be hosted here.
Remember that Wikisource often needs PDF or DjVu files in order to proofread or create source texts: Therefore, scans of suitable editions of notable public domain works are almost always within scope for this reason. That said, remember that editorial decisions involved in preparing a text from several sources may result in a new copyright, so the editions used must be out of copyright themselves.
Allowable reasons for PDF and DjVu formats
[edit]- The format has been selected for convenience of printing.
- The format has been selected to allow viewing or printing of special fonts, e.g. documents in advanced mathematics or linguistics.
- The file would be within the scope of another project of the Wikimedia Foundation if it were to be uploaded in the same format to that project, for example:
- A PDF or DjVu file of a published and peer-reviewed work would be in scope on Wikisource and is therefore also in scope on Commons. Examples of in-scope documents include published books (but not vanity publishing), peer-reviewed academic papers, etc., university theses and dissertations.
- The file is a scan of a document of historic or other external significance, e.g. scans of existing copyright-free or licensed books, reports, newspapers, etc.
- The file is usable as a fixed, verifiable source document, e.g. for Wikisource or Wikibooks (appropriate fixation of content).
- The format selected provides technical advantages to at least one other Wikimedia Foundation project.
Non-allowable reasons for PDF and DjVu formats
[edit]- The format has apparently been selected by the author or uploader to prevent or to discourage the creation of derivative works contrary to Commons' aims. Such inappropriate fixation of content would include a self-published vanity article or a self-created image that the author has uploaded in PDF format in an effort to discourage others from creating derivatives.
- The content is essentially raw text; such files are not considered media files. Note that scans of existing books, reports, newspapers etc of historic or other external significance are not excluded on this ground, even if they contain no images.
- The content would be prohibited under another section; for example, promotional material is outside Commons' scope regardless of the file format.
