I cant identify any specific books on this subject. You can find tiny scraps in artillery studies by authors like Gundmundson, or Bailey. My take is this:
to 1914 the artillery officers did their own tactical intel work. Lacking much in terms of artillery doctrine their intel efforts were equally rudimentary. Either the artillery commander or one of his staff did the reconissance and evaluation of the enemy, such as it was in 1913. Some of the Balkans armies like the Serbs were better off in this respect as their experience in 1912 & 1913 gave them a few hints about the possiblities with modern artillery. This showed in 1914 when the Serbian artillery out performed the Austrian artillery in the early battles. The Serbian artillery officers were paying more attention to terrain & enemy disposition, both core concerns of the commanders intel. analysis.
