I decided to turn the original question into several questions and simplified the basic one. Many thanks to Alan Munn.
I would like to use biblatex, however I found no simple guide for beginners BY EXAMPLE.
I read this Biblatex guide?, but it is not by example.
At first I thought this question biblatex in a nutshell (for beginners) might help, but it doesn't really do that.
I hope there is someone who is willing to pick up the gauntlet and create a simple guide by example, without general option, but with many sample different types of citations really written. (Feel free to revise the question top to bottom in order to provide the simplest guide for beginners as an answer. I'm willing to contribute as much as I can)
The bibliography is in a
.bib file, of course.
My own citation style needs are rather traditional. I need a simple author-year like AuthorLastName (1995). I can use a possessive version of citation: AuthorLastName's (1995) (the 's should be added by a suitable command). Parentheses citation (ALN (1995)) might be easy to achieve manually if it is complicated. From time to time multiple authors citation like AuthorLastName, ALN2 and ALN3(2001) may be found helpful, as multiple authors by the first author last name like ALN et al. (2002) should be available. Multiple citations for the same author(s): ALN (2003,2004) looks like an integral part.
