Can I just put add the original sources, do I have also track its current or past status?

Yes, but… you would not get the “credit” for a full entry.  A full entry is the name of an original source, sequential sources, AND the most current related source.  However, you might want to start by putting in the original source then go back to complete the entry.  If you want to partner with someone: you may enter the original source (cataloging skills are needed to create a good record) and someone else may investigate its fate.  Remember to put your name in the Extra Field.
