Over the last couple of years, I have grown disatisfied with CDs as a way to return audio interviews to narrators. In terms of reciprocity, I want to use whatever medium is most convenient for narrators.
Younger narrators have preferred email and older narrators have preferred CDs. Interviews that run longer than 80 minutes, however, must be burned as data CDs, which makes them playable only with a computer. Newer computers don't have CD drives and many of my older narrators don't use computers. Likewise, flash drives/email won't be useful to those without computers. The benefit of the CD is that it's a labeled object that will be encountered in the future by the narrator or the narrator's friends/family.
I'd love to hear what individual oral historians and various archives are settling upon as the preferred medium.
I run several workshops over the summer. While I will advise students to use the medium most meaningful for their particular narrator, I need to settle upon one method for the workshop interviews.
Many thanks for your thoughts,
