When adding a new bibliographic source to a Word document, Word offers a form in which you can select the type of the source and fill in specific fields. The form presented to the user is generated from a localized xml file called bibform.xml which you can find in a subdirectory of the Microsoft Office 12 directory.
At the moment 17 unique types of sources are defined:

ArticleInAPeriodical DocumentFromInternetSite JournalArticle Report
Book ElectronicSource Misc
BookSection Film Patent
Case InternetSite Performance
There are two problems with this set. First, some of the types are defined to broad. For example, Report covers both reports and thesis while they are often formatted differently. Second, some types such as Bill and Grant are completely absent. BibType tackles those issues.
BibType is a small command-line utilty which allows users to generate new (localized) bibform.xml files tailored to their own specifications. It is not only possible to add extra fields to existing types, but also to create new types. Of course, styles not aware of those extra fields and types, will not generate output for them.
When executed without parameters, the BibType tool will display a short explaination on how to use it. More information on the subject can also be found in the BibType guide.
Remark 1: adding entirely new types violates the Word bibliography schema and might result in sources not being processed correctly by applications sticking to the schema. However, Word 2007 does not require the type to be valid.
Remark 2: the types.xml included with this release generates a bibform.xml equal to the current one with one exception: the fields of the 'Misc' source type are extended to contain any valid bibliographic source field.
