JabRef is a Java program that can be used to create and edit your bibliography.
If Java-Runtime is not installed on your system, you can download and install the JRE-Installation package from the Oracle-Webseite.
Provided you have a functioning Java-Runtime, you can download the latest stable version here. Windows users will need the file
JabRef Windows Installer. Once the download is complete, you can initiate the installation by double-clicking on the file. To work with our template, you don't need to change the default settings provided via the installation process.
After starting the program, select Options and then Preferences. In preferences, go to the General menu and set the Default bibliography mode to BIBLATEX. This allows the database to contain additional fields.
Click on the OK button to save the settings. You can now begin to work on your bibliography.
In the default settings for JabRef, special fields such as Sortkey are not shown on the interface. Select Options and then Setup general fields. A dialog box is shown which shows the visible fields for each category. Enter the custom fields, separated with semicola. For example, if in the General view you would like to edit the fields Sortkey and Sortauthor, add to the end of the line General the character string
Click OK and you will find under the category General the fields Sortkey and Sortauthor.
