On the Edition display, can things like Book, Writer, Editor, Format, Pages / Font, etc., appear as Headers instead of a left-hand column? Either that, or fix the left-hand column width and allow line breaks. Look what happened to Major British Writers: Shorter Edition - Books - ctlgs . The contents are almost unreadably squished (Yes, I know, they are incomplete. Work in progress.)
The main problem is Library of Congress Catalog Card Number shoving everything over. Another option would be to shorten such terms, e.g., LoC Cat. Card No.
