What are the search fields in the CBNB database?

You can create a Quick search query by selecting the following individual fields from the drop-down:

• All Fields
• Subject/Title/Abstract
• Abstract
• Title
• ISSN
• Source title

Refer to the descriptions in the sections below for further information about these individual fields.

This field contains a brief summary of the entire document. To search for an exact phrase in this field, enclose it in braces or double quotation marks.

The accession number is a unique identifier assigned to a document in a database. CBNB contains alphanumeric accession numbers that begin with three letters (e.g., TCD) and contain 10-digits.

The ‘All’ field is a composite field that includes all other fields in this FAQ (except those listed in the bullets below). Therefore, using this field in a search query retrieves results from all the other fields listed in this FAQ except for the following:

This field may contain website and other contact information for the company that is mentioned in the Engineering Village document.

CAS Registry Numbers are numerical identifiers assigned by the Chemical Abstracts Service to chemical substances. On the record page, click the link(s) for the CAS registry numbers (with their associated chemical names as applicable) to search for all Engineering Village records that contain those CAS registry numbers.

Search for documents in Engineering Village using the acronyms for various chemicals using this field.

The CODEN is a unique six-character alphanumeric identification code for the source title. CODENs can be used to limit results to a specific source. CODENs are administered by the International CODEN Service at CAS.org (Chemical Abstracts Service). You can see a source's CODEN on the record page.

All companies for which information is given in the abstract are indexed. The legal designations of a company's status are not used in indexing; for example, ICI is used rather than ICI PLC.

Subsidiaries of multinational companies are separately named. The parent company will be indexed if it is mentioned in the abstract, but there is no automatic linking of subsidiaries and parents.

Full names are not reversed, but initials in company names are reversed.

Controlled terms are a list of subject terms assigned by indexers to describe the content or subject area of the document in the most specific and consistent manner. These terms can be identified by using the ‘Controlled term Browse’ index. These terms contain links on the record page. Click the links for any of these terms to retrieve documents spanning the default time period of this database.

Search this field to find documents via the country in which the document originated.

This field contains the item type (e.g., book, journal article, press release) of the document. You may also search the document type via the ‘Document type’ dropdown filter on the Quick search form after conducting a Quick search query.

This field contains keywords that describe various sectors of industry.

The International Standard Book Number (ISBN) was previously a 10-digit number and is now a 13-digit number that uniquely identifies a specific title and edition of a book or a book series. The number can be used to find chapters from the same book or papers from the same conference. The ISBN appears on the record page.

The ISSN (International Standard Serial Number) is a standardized international alphanumeric code that is a unique and precise identifier for a serial publication. The format of the ISSN is an 8-digit number, divided by a hyphen into two 4-digit numbers. The last digit, which may be 0-9 or an X, is a check digit. It can be used to limit search results to a specific journal or serial conference proceeding. The ISSN may be displayed with or without the hyphen, and can be searched with or without it. The ISSN is displayed on the record page. There may also be an E-ISSN displayed, which is assigned to the electronic version of a serial.

Search for the language of the document via this field. You may also search the language of a document via the ‘Language’ dropdown filter on the Document results list after running a Quick search or the ‘Language Browse’ index on the Expert search form

Standard Industrial Classification (SIC) codes are four-digit numeric codes that classify a company's industry group based on its business activities. The first two digits represent the highest level of classification, and the remaining two digits represent more specific classifications.

Search this field if you want to identify source titles, such as journals, books, or conference proceedings, from your area of study. Search the Source title by single words or phrases. When searching for a source title, it is recommended that you use the ‘Source title Browse’ index, as there can be several variations of a publisher's name. This index also includes books and conference titles.

To conduct an exact source title search, enclose the full title in braces or double quotation marks:

‘Subject/Title/Abstract’ is a composite field that retrieves results from any of the following component fields:

• Abstract
• CAS Registry Number
• Company Name
• Industrial Sectors
• Industrial Sector Codes
• Title

Title searches for words that appear in the title (or English translation title) of the article. This is very useful if you are looking for articles on a very broad topic. Words in a title are often an indication of the importance of those terms to the article.

You can restrict your document search to a specific publication year. You can also restrict your publication year searches via the ‘Add year range’ dropdown filter on the Quick search page and the ‘Date’ dropdown filter on the Expert search page.
