In general, housing different audiovisual formats in the same box is fine, as long as they’re packed in such a way that allows each format the correct physical orientation and that prevents items from becoming disordered. However, there are some important things to keep in mind.
- Acetate-based formats, such as film and audio reels pre-dating the 1970s, should not be housed with other formats. The off-gasing (vinegar syndrome) could be harmful to other formats.
- Phonodiscs are often difficult to pack along with other formats, as it’s critical they remain as close to standing up straight as possible. Best to avoid housing phonodiscs with other formats.
