Referencer is a Gnome application to organise documents or references, and ultimately generate a BibTeX bibliography file. Referencer includes a number of features to make this process easier: * Smart web links Referencer uses documents' metadata to provide handy links to the document's web location — no need to maintain your own bookmarks. * Import from BibTeX, Reference Manager and EndNote No need to start from scratch — Referencer will import your existing bibliography files using the BibUtils library. * Tagging No need to organise your documents into rigid directory trees — with Referencer you can use tags to categorise your documents. * Automatic arXiv, PubMed and CrossRef metadata retrieval If you show Referencer a PDF which has an arXiv ID or DOI code, Referencer will retrieve the metadata for this document over the internet. * Python plugin support Referencer can be extended using the versatile Python scripting language. * Localisation
