It appears to be part of BFI's TV Classics series... which I'm afraid I'm not terribly familiar with. Anybody familiar with them at all?
I don't have any of their TV Classics books (yet), but I have a number of their film books. They're smallish paperbacks, averaging maybe a hundred pages, critiquing/analyzing movies or TV shows in an academic but accessible style.
Ina Rae Hark was one of the relatively early academics to write about Star Trek, with an article in Extrapolation in 1979. She also contributed an essay to last year's The Influence of Star Trek on Television, Film and Culture, a book edited by Lincoln Geraghty.
Here's what BFI's website says about the book:
Star Trek remains the original, iconic and, for its many fans, the best example of science fiction television, boldly going where no TV drama had gone before. Ina Rae Hark's lively and authoritative account of the five series -- from the original Star Trek to its most recent manifestation, Enterprise -- provides a comprehensive guide to the Trek universe and its key themes.
Hark carefully delineates the unique characteristics of each series, from Star Trek's depiction of humanity confronting technological and evolutionary change, to The Next Generation's diplomatic efforts to secure its perfected utopia for others, Deep Space Nine's interrogation of the claims of that utopia in a hostile, alien environment, Voyager's testing of Starfleet principles light years away from the Federations borders, and Enterprise's look back at humankind's first efforts to forge an intergalactic alliance. Hark explores the character dynamics of each captain and his or her crew.
As well as offering new insights for even the most hardcore Trekker, this volume also provides a perfect introduction to a popular culture phenomenon for those few who have never heard of a phaser or a Klingon.
FWIW, you can always find info on nonfiction Trek books like this (as well as fiction) on my website.
