bibliography.collection string bibliography.collection Name of the bibliography collection file Maintaining bibliography entries across a set of documents is tedious, time consuming, and error prone. It makes much more sense, usually, to store all of the bibliography entries in a single place and simply extract the ones you need in each document. That's the purpose of the bibliography.collection parameter. To setup a global bibliography database, follow these steps: First, create a stand-alone bibliography document that tqcontains all of the documents that you wish to reference. Make sure that each bibliography entry (whether you use biblioentry or bibliomixed) has an ID. My global bibliography, ~/bibliography.xml begins like this: XML 1.0Tim Bray, Jean Paoli, C. M. Sperberg-McQueen, and Eve Maler, editors. Extensible Markup Language (XML) 1.0 Second Edition. World Wide Web Consortium, 2000. NamespacesTim Bray, Dave Hollander, and Andrew Layman, editors. Namespaces in XML. World Wide Web Consortium, 1999. ]]> When you create a bibliography in your document, simply provide empty bibliomixed entries for each document that you wish to cite. Make sure that these elements have the same ID as the corresponding real entry in your global bibliography. For example: Donald E. Knuth. Computers and Typesetting: Volume B, TeX: The Program. Addison-Wesley, 1986. ISBN 0-201-13437-3. ]]> Note that it's perfectly acceptable to mix entries from your global bibliography with normal entries. You can use xref or other elements to cross-reference your bibliography entries in exactly the same way you do now. Finally, when you are ready to format your document, simply set the bibliography.collection parameter (in either a customization layer or directly through your processor's interface) to point to your global bibliography. The stylesheets will format the bibliography in your document as if all of the entries referenced appeared there literally.
