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. biblatex with 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:
style=readingwill simply override any style choosen previously. "Tweaking" thereadingstyle to your liking is probably more difficult than fixing the missing space between author and title shown in your first screenshot. With regard to this screenshot: Please provide a compilable example that shows the faulty behaviour instead. I tested my example with thehyperrefpackage added, and things still work as expected. – lockstep Jun 19 '11 at 09:49l.7850 \blx@processoptions ------- It might be a problem with this Latex/Biblatex installation? Thanks @lockstep
