Thanks, Bruce and John. Indeed, I used biblatex with natbib=true option, which gives me citet and citep in biblatex. But using \autocite and \textcite is perfect.
I am noticing a few other issues at this stage. I have a large biblatex database, and loading it using C-c C-x @ to insert citations seems very slow (have not managed to load it thus far). Org-ref used to be much faster in this. org-cite works fine with a smaller biblatex database. I don't know if others have had the same experience. I understand that oc-biblatex.el loads biblatex in the background, produces the citations and the bibliography, and inserts them in the exported output. In that case, what are the possibilities of using biblatex commands to configure the output? I realise that these will not work since most of it would be LaTeX specific. Does that mean the users will have to work with CSL styles to format the output even if they are using oc-biblatex.el? I am still somewhat confused about how this is going to work. I notice that there is an option org-cite-biblatex-options which can be customized to load biblatex with specific options. I have not yet managed to test it. If somebody has already played around with it, it would be useful to know what they could manage to do. In my experience, biblatex and bibtex uniformly process the author names whether they are written in the database file as "John Kitchin" or "Kitchin, John". This does not seem to work with oc-biblatex.el at least out of the box and the two are formatted differently. Thanks again, Vikas
