ID Number Search in Advanced Search

Each IndexCat record was assigned an unique ID Number during conversion of the item from the printed Index Catalogue. Originally designed to assist quality control, the ID Number continues to be useful because of the intelligence in its structure.

You can use the ID Number to:

1. Retrieve a single citation from IndexCat

2. Check the online citation against the printed Index Catalogue

• The ID number guides you to the correct Index Catalogue series, volume, page, and relative position on the page.

Structure of ID Number

The ID Number is an eleven (11) digit number. It is divided into these seguments:

• position 1: Series number (1-5)
• position 2-3: volume number within the series
• position 4-7: page number in volume
• position 8-10: item number on page (assigned during conversion)
• position 11: NLM sequence digit (place holder)

Example:

• ID Number: 30406931150 -- (bold separates number seguments)
• 3 = Series 3 -- Series number (1-5)
• 04 = volume 4 -- volume number within the series
• 0693 = page 693 -- page number in volume
• 115 = 115 -- item on page (assigned)
• 0 = -- place holder

To perform an ID Number search:
