Star Fleet Medical Reference Manual
© 1977 Paramount Picture Co ISBN 0-345-27473. A reference book of various medical information from the 23rd century covering chemistry, anatomy, history, alien flora and fauna, as well as first aid. As usual Memory Alpha is much more complete than I am willing to be.
This is another book that is long out of print. It never enjoyed the popularity or reprints that the other technical manuals had. It can be acquired without spending buckets of cash if one is interested.
