OldSoldier - it can be done, you need to copy the folder
..\Calibre2\resources\catalog from the calibre install directory to the
\resources directory in the calibre configuration directory.
On my setup that's copy
C:\Program Files\Calibre2\resources\catalog into E:\CalibreData\calibre\resources (yes, I moved the config data out of %APPDATA%)
In the catalog folder you'll find a file
template.xhtml. In there you can tailor the catalog to your requirements - eg replace the pubdate column with your #datewritten column. You'll probably want to format the date, you can do that via the template, see format_date in the template tutorial ==>>
The calibre template language
The way the 'resources' folder seems to work is that calibre looks for things in the config folder first, and if its not there, it uses the default in the install folder. Very simple, and effective solution.
