There are writers who seem to keep everything including receipts and others who systematically destroy any data outside the published work itself. On this spectrum there are those who hold onto some material and those who tend to lose or misplace things (like John Forbes). I fit somewhere in the retentive end though I can understand those who want nothing but the authorized work to be available. Most of us will leave at least some work out of later collections: this is how we wish to present ourselves. At the same time anyone can go back and find the discarded items if they want to, and I have no problem with this. With writers whose work I love I want to see as much as I possibly can; even the failures can be of interest. But if I had to put together an edition of another author’s work I would feel (unless the edition was ‘scholarly’) that I was doing the author a disservice in including second-rate work.
