This is a full list of extracts from primary sources in *Wherever We Are When We Come To The End*, intended to supplement the short list of explanatory notes in the published volume. I have not included passing references or allusions – in one sense the whole poem is an allusion to the *Tractatus* – but if you notice any substantial quotations not cited here or in the volume please let me know and I’ll add them to the list. References are listed by page and propositional number in the poem, and employ the following abbreviations:
