LibreOffice is a free and open-source office suite developed by The Document Foundation as a fork of OpenOffice.org. It is largely compatible with other major office suites, including Microsoft Office (MS Office) and is available for a variety of platforms. It is the default office suite used by Ubuntu and many other popular Linux distributions such as Fedora.
LibreOffice can import/export documents in several file formats; its native formats are the OpenDocument Formats (ODFs) such as OpenDocument Text (
.odt), OpenDocument Presentation (
.odp), OpenDocument Spreadsheet (
.ods), etc. Formats supported (for reading and writing) include the Office Open XML specification used in Microsoft Office 2007 and 2010 (
.xlsx), as well as to the older file formats used in Microsoft Office 95 and 97-2003 (
.xls). It also supports Rich Text File format (
.rtf) and OpenOffice.org XML format. All documents can be exported to the PDF format (
.swf). LibreOffice also has the ability to import documents in read-only mode in the Uniform Office Format, Data Interchange Format and the formats of Microsoft Works, WordPerfect and Lotus 1-2-3.
Citations in LibreOffice can be managed with plugins for the citation managers Mendeley and Zotero.
