Whilst rummaging around on the BAA website I found a book review by Lee Macdonald from 2010 of Wolfgang Steinicke’s book Observng and cataloguing nebulae and star clusters”:

The hardback edtion then was £90, and online today a new copy is over £100 (though second hand copies available for nearer £60), but there was a reprint in a paperback edition in 2017 which is only £40 new.
It has to be regarded as a one of the great works on the brighter deep sky targets and like Burnham’s Celestial Handbooks is much more than just a list of what is out there, it is also a tremendous reference text on the discovery of these targets and an important book in the history of astronomy of the deep sky.
Well worth the £40 I would say.
