Hi Eva,
SAP MDM SP08 documents wont be available since these are outdated now. Its wont be possible to track older version as soon as the new version is released. You might want to check with friends/teammates to email these documents. Or share your email address so that someone over forum could email SP08 version reference guides to you. Nevertheless you can still use SP12 documents for learning more functionality.
Regards,
