There are numerous books about performance practices in general (including ornamentation) pertaining to the musical styles of various eras; some are limited in scope to a particular aspect of interpretation, historical genre or musical instrument.

Ornamentation, A Question and Answer Manual, by Valery Lloyd-Watts and Carole L. Bigler, is specific to ornamentation but otherwise broadly applicable.

Ornamentation in the Works of Frederic Chopin, by John Petrie Dunn (currently out of print), is an example of a highly specialized title.

The 'Ornamentation' book mentioned is pretty easy to read.

CPE Bach and Quantz wrote extensively on ornamentation - both available in translation.

If you use the Alfred publication series, Willard Palmer has  information on Baroque ornamentation in his Baroque music books......Bach, Handel, and Scarllati. Great source.
