LibreOffice is a suite of programs for word processing, spreadsheets, presentations, databases, and vector drawings. It is free to download, use, and distribute. It is available in many languages and runs on Linux, Mac, and Windows.
LibreOffice’s native file formats are OpenDocument (*.ODT, *.ODS, *.ODP, etc.), but it can open and save to many other formats, including Microsoft Office formats (*.DOC, *.XLS, *.PPT, etc.).
To download LibreOffice, go to the LibreOffice website.
LibreOffice is a project of the not-for-profit organization, The Document Foundation.
A short introduction to the software is Introducing LibreOffice (PDF). For more detail, get the full book Getting Started with LibreOffice (see links in lefthand sidebar).
Bruce Byfield’s much-anticipated book, Designing with LibreOffice has been published by Friends of OpenDocument, Inc. Read about it here or jump straight to the download/buy page to get a free PDF or buy a printed copy.
Carla Schroder, Author of The Linux Cookbook, The Linux Network Cookbook, and The Book of Audacity, says this about the book:
“Designing With LibreOffice” teaches everything you need to know about document production: chapters, footnotes, citations, indexes, outlines, cross-references, incorporating images and spreadsheets, and controlling the appearance of your documents. It is well-organized and contains abundant examples, and is suitable for beginners to wizened old pros, who will probably discover things about LibreOffice that they didn’t know.
