yes self-citation of previous work can be added in case of new work related to previous one.

RG has allowed me to self-cite my published article into what they call a "Technical Report" of mine, in other words, into one that is not published.

I was surprised, but I guess the Technical Report is citing a publication: Maybe this "Report" may get published eventually and the citation will still hold. If it does not get published, still it is a report and cites some work, so it is valid in a way.

It is my belief that self-citation is alright. However, I do not believe it should be a part of the RG factor.  It is easy to understand how authors could cite their various papers in many papers and build up their RG factor.. Does not make sense  to me. My opinion, of course

Thanks for the inputs Paul and Issigonis. Its worth to hear this from such experienced researchers now that I am just new in the field and struggling to get even a single citation. I attended a workshop and its true what they told us ..that those who are cited most are bound to be cited over and over again and those with no citations have fewer and fewer chances of being cited! and this can be very frustrating to young researchers.what's your take on this?

On self citations, I thought that maybe if you are building up on work that you previously did or using a method that you have published before, then you can cite your previous works?

Hi Becky, I have never worried about citations. I know that I have more citations but I just leave things the way they are. No problem for me. But a  young researcher like yourself you need to build up your citations, mainly by self-citation.  What is most important is  that you write excellent papers that will be cited by others. Best wishes, Paul.

Becky,

All but one of my citations were "gained" by my co-author (who was the principal author), therefore, was I a failure as far as citations go?

I don't know, but I did not pursue them in my career, which involved mineral exploration and then university teaching. As you see I had various occupations which I enjoyed thoroughly and I don't regret not getting this or that including citations.

Just pursue whatever your interests tell you to do, if you can find the job you want and the career you want to follow: and BE HAPPY!

You are doing very well!

Yes, Self citation is allowed 

Is self citation or referencing allowed in research?

Self citation is allowed in research.  But we need to self-cite consciously i.e. when it is related / relevant in context.  We shouldn't put self-citation as one of the goals when writing an article.

Thank you very much for the insight Han Ping Fung

As far as I know,  pull out some old literature which has at least slight similarity in case of your work or predictions. That will be helpful when people examine. In our place its mandatory that you quote something similar from other literature. And finally you can say how novel your finding is.

Yes, self-citation of relevant work is allowed and should be cited.It shows your expertise in that field.

What is the problem in this? If the current work is related to or continuation of the previous work, there should not be any hesitation to mention the same. It should not be regarded as either self acclamation of flamboyance.

Yes, there in nothing wrong with self-citation of previous relevant articles.

A moderate amount of self-citation is often inevitable for researchers who are active in a research topic for long and  continue on their previous studies. However, excessive self-citation can be considered unprofessional. If the percentage of self-citations to the total number of citations  is high and close to 1, that is excessive! .

I agree with Rathore and Jayaraman, for up-gradation of the research on same aspect or other aspects of the research problem such self-citations are necessary..

I am grateful for all the answers that have been provided here to try and shade some light on the issue of self citation. One thing I have noted is that all of they do suggest that self citation or self referencing is allowed in cases where you want to build on your previous research and must refer to tit in the process. However, I have also noted that this shouldn't be our key motive..to self cite so as to build our reputations based on the numbers of citations. Thanks all!

Although authors may have good reasons to cite their own works, these citations do not necessarily reflect the importance of their work or its impact on the rest of the scientific community.

- If some of your previous publications are relevant to your new research, you have full rights to self-cited your previous work as well as other's work.

- Self citation is allowed to show your previous experience, but take care to put most-relevant publications to the new one.

- It mustn't be your aim to cite so many publications of your previous work to raise your citation index. 

If your research work is new and unique you can cite your work. But it should be limited. 

Dear All,

Self citation should not pose any problem and be permitted as a general rule.

As already stated by George and other contributors, citing your previous work from which your current stems is both ethical and acceptable. However, excessive self citation is unethical and to me, prevents readers from comparing your work with other researchers'. Thus, robbing them of the opportunity to make an unbiased and informed judgment of the significance of your work.  The bottom line, therefore, is self citations should only be done when absolutely necessary.

It is nothing wrong in self quoting. You should not forget to quote the works of others also. Please do not waste your time. There are so many things to be discussed. I do not believe in citation, impact factor ,acceptance and rejection of Papers by Journals. Rejected by one Journal , The paper is accepted by other Journal. Please encourage all types of original / New works even when they are very small.

Thanks Susai Rajendran. Whether the results are negative or biased, it should be published. However, self-citation is accepted and it depends the research domain and how many others cited your article

Nothing wrong in self-citation if it is really worth doing so.
