Work aliases allows us to have variant names, but not to determine where those variant names are used, which is insufficient.
What I believe would be the ideal solution would be to have a table of contents that allows to express which work appears at what page and under what name.
Another solution would be to have variant names for relationships.
This would allow for fine-tuned descriptions such as “Edition X contains Work Y as Z” where Z is the variant name as it appears in that Edition.
The merits of this approach is that it allows solving similar issues for other entities (for example “Work X was written by Author Y under the pseudonym Z”).
