remove "In" field from bibliography

Question

I want to cite an archive paper, which doesn't have a journal name. If I do something like this,

@article{article,
    author    = "Author",
    title     = "Title",
    year      = "2003",
    url   = "arXiv:000112"
}

my bibliography get generated like this:

Author. “Title”. In: (2015). URL : arXiv:1409.1556.

There"s no journal name in front of In. Is it possible to simply remove this "in"?

Answer 1

You could use "@unpublished"

@unpublished{key,
  author = "Author",
  title  = "Title",
  year   = "2003",
  url   = "arXiv:000112"
}

which gives:

Author. Title. 2003. URL arXiv:000112.

Answer 2

To specify the Entry Type use the following syntax

\renewbibmacro{in:}{\ifentrytype{article}
    {}
    {\bibstring{in}\printunit{\intitlepunct}}
}

where you can replace "article" with any Entry Type (book, collection, periodical, proceeding . . .).

The empty braces in the second line means replacing "In:" with empty, thus deleting it (Note: you can replace the word "In:" with any other word).

"\bibstring{in}" it's just the word "In", and "\intitlepunct" it's the two points of "In".
