Perhaps you should try some spelling variations:
"information structures book" » "information infrastructures book", "information infrastructure book", "information structures block", "information structures blood", "information structures bloom"
"information structure book" » "information infrastructure book", "information structure boom", "information structure block", "information structure bank"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"information structures book\") OR (\"information structure book\"))".
• Removing quotes may allow a broader search: (( information structures book ) OR ( information structure book )).
• Adding a wildcard symbol may retrieve word variants: (("information structures book") OR ("information structure book"))*.
