- Publisher’s version
- 	*European journal of medicine Volume 3, Number 5 July 1998*
- Database version
- 	*European journal of medicine Vol. 3, No. 5 July 1998*
- User’s citation
*	**Europ. J. Med. 3 (5) 1998*, *34-75*

## Multi - Part Searching

- Pattern may be available in:
- MARC 21(USMARC)  - 853-855
- If unknown origin can:
- send unparsed citation to server - lack confidence in results
- send only chronology search
- send enumeration captions - unreliable

## Requesting the pattern

- Present request for GRS1 and pattern schema
- Origin may present pattern to end user for completion or:
- convert the keyed citation to pattern schema elements

## How is it used?

- Direct search on a holdings database
- count indicates number of holdings matching
- may include bibliographic record depending on the ESN

## As part of a search on a bibliographic database
search a mixture of bibliographic & holdings attributes
count indicates number of bibliographic records
one holdings record per bibliographic record
may include holdings not matching search criteria
