The PLUS StandardsPLUS Glossary of Picture Licensing
The PLUS Glossary puts into standardized language over 1000 licensing terms, definitions and uses, all
mutually agreed upon by the widest and most diverse worldwide coalition of organizations and industry
professionals in the history of image commerce.
