What citation style is this?

Question

I need the following bibliography style I looked up different citation styles but I could not find something similar.

In the text, the citations are marked with a footnote (should no be longer than one line).

Eg: For books we have². For journal articles we have³. For an online resource, we have the following style$^4$. (I don't know how to use LaTeX on TeX.StackExchange :D).

---

²Einstein, A.; Bohr, N.: Some epic book (1920), S. 20-25.

³Euler, L.: Some epic math equations (1770).

${}^4$Solid Snake: How to clone your brother (2003).

In the Bibliography, it should look like the following (without so much space after the boldface part and the non-boldface part.

Einstein, A.; Bohr, N.: Some epic book (1920)

Einstein, A.; Bohr, N.: Some epic book, Springer Verlag, New York, 1920

Euler, L.: Some epic math equations (1770)

Euler, L.: Some epic math equations, in: International Conference in advanced Epicness, Vol. 31, S. 641-651, 1770

Solid Snake: How to clone your brother (2003)

Solid Snake: How to clone your brother, https://www.SolidSnakeBlog.com, 2003, Zugriff 01.01.2007

The URL should not be marked like in my post. It should be displayed as plain text. Zugriff 01.01.2017 is just the date at which I accessed the resource. and S. 20-25 is the German version of p. 20-25.

Question: It would be helpful if someone could help me out on this weird citation style. The people from the institution that forces me to use his citation style said that I should rather use Word (for which they have a template that does this weird citation style) because LaTeX would not support such a citation style. I am pretty sure LaTeX can even handle this but I could not find anything similar to this.

Answer 1

I am not aware of a readily available style that gives exactly the output you need. The combination of author-title citations with year is quite unusual as far as pre-built styles in LaTeX are concerned. Here is a start with biblatex-ext.

Most things used here should have names that tell you more or less what they do. If it is not clear what the commands do, a search in the biblatex manual and the biblatex-ext documentation should hopefully clear things up.

There are probably a few more details that need to be fixed. Guidelines for customizing biblatex styles is a great post to get started with those.
