Hints:

For subheadings that overlap those in the SCIENCE section, use subjects in this section for works dealing with practical applications and use subjects in the SCIENCE section for works of a theoretical or historical nature.

Use subjects beginning with "TECHNOLOGY & ENGINEERING / Agriculture" for works aimed at farmers or agronomists (or for general works on the specified topics). For works on practical operations in the cultivation of fruits, vegetables, flowers, and ornamental plants, use subjects in the GARDENING section. For works on the commercial cultivation of fruits, vegetables, nuts, and ornamental plants, use "SCIENCE / Life Sciences / Horticulture".

Use subjects beginning with "TECHNOLOGY & ENGINEERING / Construction" for works concerning the technical or trade aspects of construction. For historical works and/or works aimed at architects or design professionals, use subjects in the ARCHITECTURE section. For similar works aimed at nonprofessionals, use subjects in the HOUSE & HOME section.
