4 months ago I asked this question and emailed ESRI staff. I have yet to receive a reply or an answer.
October 2015 I attended a workshop on the creation of the Historic Map Collection viewer. At the workshop we were told all resource files (MXD, custom toolbox with 3 scripts, data template) would be available on ESRI.com.
NOTE: I am not talking about the GitHub repository for the application files. I have those. What I am looking for are the resource files for the map compilation workflow.
I have searched the ArcGIS website extensively with no success. I have found the ArcGIS Online map Historic Map App
but the Details page has no information for the resource files.
I can survive without the data template and MXD but I really need the toolbox and python scripts: Add Feature Class Indexes, Add Mosaic Dataset Indexes, Create Envelopes.
Supposedly there was to be a .zip file containing all of these resources available at ESRI.com
