Use of images within a book - copyright issues
I have a general question on the use of images within a book, in particular copyright/public domain images.
I am producing a book on British rock 'n' roll in the 1960's in which I would like to include images of various artists. I have my own copies of concert programs from that period which include publicity shots of the artists. What's the opinion of fellow Lulus on using scanned copies of these images in my book - providing I include where the images came from?
As far as I can tell there are no copyright marks on either the programs or the photos so I am unable to contact the photographers/publishers directly.
