There's no consistent format for book review titles appearing in various periodicals. Across the Summon index, one sees entries like:

• {author name} {book title}
• {book title}
• Review: {book title}

and all manner of different combinations of these elements. Unfortunately, OpenURL linking to destination databases fails unless both sources agree upon the format of the title. Summon describes book review titles one way and it might match some databases, many it will not. Links from Summon to ProQuest databases don't even work consistently (see attachment).

Summon needs an approach superior to naive OpenURL linking or poorly formed searches using title metadata. Often, plenty of non-title metadata uniquely describes the item in question (date, issue, volume, and starting page rarely have the same disagreement issues as textual data).
