Master Documents and Sub-documents

A master document lets you manage large documents, such as a book with many chapters. The master document can be seen as a container for individual LibreOffice Writer files. The individual files are called sub-documents.

Characteristics of Master Documents

Note Icon

When you add a document to a master document or create a new sub-document, a link is created in the master document. You cannot edit the content of a sub-document directly in the master document, but you can use the Navigator to open any sub-document for edit.

Example of Using Styles

A master document master.odm consists of some text and links to the sub-documents sub1.odt and sub2.odt. In each sub-document a new paragraph style with the same name Style1 is defined and used, and the sub-documents are saved.

When you save the master document, the styles from the sub-documents are imported into the master document. First, the new style Style1 from the sub1.odt is imported. Next, the new styles from sub2.odt will be imported, but as Style1 now already is present in the master document, this style from sub2.odt will not be imported.

In the master document you now see the new style Style1 from the first sub-document. All Style1 paragraphs in the master document will be shown using the Style1 attributes from the first sub-document. However, the second sub-document by itself will not be changed. You will see the Style1 paragraphs from the second sub-document with different attributes, depending whether you open the sub2.odt document by itself or as part of the master document.

To avoid confusion, use the same document template for the master document and its sub-documents. This happens automatically when you create the master document and its sub-documents from an existing document with headings, using the command File - Send - Create Master Document.
