 and high-res pictures for print. When there are requirements that force the
 size of images in our document to change, the fun will probably be gone.
 
-Hopefully TUGboat will accept an article accompanying this description. 
+There is an article in TUGboat (\url{%
+  https://www.tug.org/members/TUGboat/tb37-3/tb117willadt.pdf}) accompanying
+this package, for now (january, 2017) it is only available to TUG members; a
+public release will follow at the beginning of 2018, as with all TUGboat
+articles.

+\subsection{Similiar Work/Prior Art}
+
+There have been prior attempts to do similiar things. I found
+\texttt{degrade.sty}\footnote{see
+  \url{http://mirror.ctan.org/graphics/degrade}} 
+ and an equivalent con\TeX t module, there are at least two threads on
+ stackexchange\footnote{see
+   \texttt{http://tex.stackexchange.com/questions/14429/\\
+pdftex-reduce-pdf-size-reduce-image-quality}
+and 
+\texttt{http://tex.stackexchange.com/\\questions/2198/how-to-create-small-pdf-files-for-the-internet}}
+ and there had been, as
+I have learned, some work by Axel Berger and others, posted 2011-03-31 on
+\texttt{de.comp.text.tex}. 
+
+But what motivated me most to find something better than scaling pictures
+individually was seeing that Adobe InDesign\textregistered\ does
+scale graphics according to the output intent.
