Merging error of The Philadelphia Adventure

[Zinnober 9]

Greetings, I found that there is a merging error on two of Lloyd Alexander's books The Philadelphia Adventure and The High King. The Philadelphia Adventure has incorrectly been described as The High King, and both are labeled as being the fifth book in BOTH the Vesper Holly series AND the Chronicles of Prydain series together. They are not the same book, nor are they from the same series and should not be combined or merged in any way. The High King should be listed as the fifth book in the Chronicles of Prydain series only, (not both) and The Philadelphia Adventure should be the fifth book in the Vesper Holly series only (not both).

While the only thing wrong with The High King’s page is that it's listed as being in both series, the plot, alternate title(s), characters, literary awards, and most of the “other editions” listed are all incorrect for The Philadelphia Adventure and belong to The High King only. All the editions of The Philadelphia Adventure have the problems stated above except for this one: The 1992 edition by Yearling (The Philadelphia Adventure) has the correct plot, but all of the other errors. The published (and published by), page length, binding, the ISBN, and the ‘edition language’ details all seem to be correct on all editions of The Philadelphia Adventure however.

Also related, on this page: Vesper Holly series the The High King has erroneously usurped The Philadelphia Adventure's place on the list and The Philadelphia Adventure (which should be on this list) is nowhere to be found.

Could someone please fix these errors?
Thank you!

Thank you Kariema! That looks better, but the The High King is still saying that it's part of both series, and The Philadelphia Adventure is still missing from this page.

Copying the plot description from this edition The Philadelphia Adventure and adding it to the edition that comes up most The Philadelphia Adventure would be good too.
Thanks!
