Property Fields1)
In NTIS a numeric search for a specific set of physical properties (/PHP) is available within the text fields (TI,AB, BI). The numeric values are not displayed as single fields, but highlighted within the hit displays.
Use EXPAND/PHP to search for all available physical properties. A search with the respective field codes will
be carried out in all database fields with English text. The /PHP index contains a complete list of codes andrelated text for all physical properties available for numeric search.
