Classification codes let you search business-targeted databases such as ABI/INFORM, Banking Information Source, and ABI/INFORM Dateline. The classification codes segment these databases into broad topical areas.

When you use the codes with search words, classification codes are a fast way to precisely target a search by topic, industry or market, geographical area, or document type.

You can quickly add classification codes to your search by using the Look up classifications link.

Using the Look up classification codes to Focus Your Search

ProQuest gives you an easy way to focus your search within specific industries by using the Look up classification codes link. To add a specific industry to your search from a Basic Search or Advanced Search:

1. Click the More Search Options link.
2. Select the desired operator to use when adding the industry from the drop-down menu before the Classification code field.
3. Click the Look up classification codes link next to the Classification code field.
4. Click the category that contains the desired industry. You see a list of subcategories and industries related to the category you chose.
5. Click the subcategory that matches the information you want most closely.
6. When you've reached the end of the hierarchy, you will see Add to Search next to the industries that can be added to the search.
7. Click Add to Search next to the industry you want to add to your search.

Using Classification Codes to Find Documents

You should use the most specific code possible. Remember, the codes don't cascade. If you enter cc(9170), your search will only find that code (Non-US) and won't find any of the codes below it.

If you want to broaden the search to include multiple codes, you need to use the truncation character. For example, to find all rules, regulations, and legislation related to pension plans, you would search for su(pension plans) AND cc(43*).

To enter Classification codes using the truncation character, you will need to enter the search values using the mnemonic, and not through the Look up Classification codes window.

Example Searches with Classification Codes

cc(2120) AND salar*
Finds documents with salary information for Chief Executive Officers (classification code 2120).

policy AND stype(newspaper) AND cc(8340)
Finds newspaper documents on utility policies, since classification code 8340 covers electric, water, and gas utilities.
