There are quite a few books on the use of symbols in communications. Most of these symbols, however, apply to nouns, not verbs, and so are of little value for our work.
Symbol Sourcebook, by Henry Dreyfuss
An
exhaustive list of symbols from a wide variety of fields: agriculture,
chemistry, medicine, industry, traffic, business, and so on. These are
all strictly black and white symbols, and I found few that could be of
use for verbs.
Visual Languages
This is an old (1986) compilation of papers from computer science. I don’t see much value in it.
Blissymbolics by Elizabeth S. Helfman
Another work of little value other than to widen the background of the researcher
Unipix, by Cindy Drolet
A
handy-dandy collection of images for travelers who wish to communicate
their desires to somebody who doesn’t speak their language. Examples:
A Dictionary of Symbols, by J.E. Cirlot
This
has almost no images; it is instead a thoroughly researched compendium
of the symbolic roles played by objects. For example, it begins its
discussion of ‘Hanged Man’ with the statement “This figure has a
profound and complex symbolism.”
The Penguin Dictionary of Symbols
This is similar to J.E. Cirlot’s book.
Dictionary of Symbols, by Carl G. Liungman This is an extensive listing of symbols from many different cultures and contexts. I have not read it; I’ve only sampled a few pages from it.
