Is it possible to customize the bibliography (at the end of the document) so that references are shown as follows:
Author_A short_title Author_A long_title
Short titles are used throughout the document.
style=authortitle-comp is used. It is difficult to relate the short titles to the normal long title in the bibliography when reading the document. It is therefore required that the author name and the short title should precede the full references in the bibliography for ease of reference.
The solution by @lockstep work, but there is one issue. The layout is incorrect in that there is not a space between the author and the title. In addition the author references are mulched. Please see the screenshot here.
Bibtex was upgraded as per @lockstep's note hereunder and all issues were resolved. Well almost ...
What can be done to get rid of the dot at the start of every reference, see the example here:
