Has a detailed version of the poem about Sigurd/Sigurth fighting the dragon Fafnir (p241-)

Sigrdrifumal (The Meeting with the Valkyrie) (p252) - Sigerdrifa, a Valkyrie, advises Sigurth when he asks her for wisdom. She proceeds to tell him eleven things he should know, from how to carve a rune in his palm when his wife is in labor to looking out for witchcraft when you go into battle. It is very Machiavellian. 

Fragment of a Poem about Sigurth (p260) - In this version, after marrying Guthrun/Gudrun, Sigurth disguises himself as his brother-in-law, Gunnar, and woos Brynhild. He sleeps with a sword between them so as not to defile her. Eventually, she finds out what is going on and commands Brynhild then commands Gunnar and his brothers to kill Sigurth. Sigurth is murdered, but the exact circumstances were part of the last poems. 

The Short Poem of Sigurth (p273) - As above, only this version depicts Sigurth being murdered in his bed. Brynhild kills herself and orders them to be laid on the funeral pyre together with a sword between them, just like their marital bed. 

The Tale of Hamthir (p333) - Guthrun's sons by her new husband, King Jonaker, are Hamthir and Sorli. Her other half-son, Erp, son of a concubine, joins them to go and kill the king of the Goths, Jormunrekk, who murdered their sister Svanhild, daughter of Sigurth. Erp gets killed by the other two brothers from a mistake. Eventually they fight their way through hordes of Goths and cut off Jormunrekk's arms and legs. But he shouts for his men to stone Hamthir and Sorli to death. They are fated to die for killing their half-brother.
