Indexing principles for Category J - Technology and Food and Beverages

Category J - Subheadings

Since the MeSH terms in Category J are divided into two broad subcategories – J1 (Technology, Industry, and Agriculture) and J2 (Food and Beverages) – the subheadings allowed with these subcategories are also divided into two groups.

The following subheadings are permitted with the MeSH headings in Category J1:

/classification /legislation & jurisprudence
/economics /manpower
/ethics /methods
/history /standards
/instrumentation /statistics & numerical data

The following subheadings are permitted with the MeSH headings in Category J2:

/adverse effects /poisoning
/analysis /radiation effects
/classification /standards
/economics /statistics & numerical data
/history /supply & distribution
/instrumentation /toxicity
/microbiology /utilization
/parasitology /virology

The subheading list above is a “basic” list of subheadings permitted with Category J terms. Other subheadings may also be permitted with a particular term if this term is also in another category. For example, the subheadings permitted with PROTECTIVE DEVICES (J1 Category) are those that are permitted with equipment and supplies. The subheadings permitted with VEGETABLES (J2 Category) are those that are permitted with plants in general.

Check the MeSH record for the list of allowable qualifiers for the particular Category J term.
