I'm using LaTeX with BibTeX to display the literature of my thesis. We have to adapt our work to several custom 'styles' from the university. That's why I want to somehow define my own styles: For each entry type the given style can be different and further, the displaying in the bibliography and in a cite is different. I don't know if it's quite 'easy' to define my own styles in BibTeX so that I could 'invent' new entry types, let's say

```
entryTypeA
entryTypeB
entryTypeC

```

and than define the style of each how to display it in the bibliography and how when citing it with `\cite{}` and how when citing it with `\footcite{}`, etc.? Something like

```
entryTypeA:
bibliography="@Autor, @Title in year @Year, @Publisher"
cite="@Autor, @Year"

entryTypeB:
bibliography="@Autor, @Year, @Title, @Address"
cite="@Autor: @Title"

```

etc. (just examples).
