Just want to know on what is the current practice of including related studies to our research: is it within the last 10 years or within the last five months. Thanks.
There is practically no limit. It varies from case to case.
If you want to perform any experiment on estimation of protein from body fluids, you have to name Lowry et al (1951). For tissue section and staining, Luna (1968), antibacterial drug testing on bacteria Buer et al (1966) like that.
In spite of several modifications, basic procedures of some research deserve referencing, particularly in the thesises of Ph D.
I think that the relevant scientific sources published within ten years are the best, but references classified as scientific books do not have a specific date.

Generally, the newer is better, however, there must still need for legacy references may be decades ago. An interesting example about that: A major reference in computer science for core algorithms is the Knuth's (The art of computer programming). This great reference depends as a reference on an algorithm from B.C.era which is [The Chinese remainder theorem].
In Ukraine, the work of a scientist is assessed by publications for the last 5 years. A literary analysis of recent advances in science is allowed over the past 10 years, but it is better if we analyze newer sources
I think research has to be assessed in totality. All related work need to be evaluated.
However to assess whether a researcher continues to be active in research, previous five years research contribution as well as ongoing research work needs to be given due importance .
I think so that there are no limits indeed. Some "historical papers" are very very interesting and inspiring. We must only get them and read patiently :-)
It depends on a variety of factors, I think. I've been a member of some thesis committees wherein the institution required that references all be within the last five years. I've worked in other places where there was no time limit. In some cases, I was also to 'just use common sense.' So, I think it varies.
It was recommended to me to not reference material older than 10 years. However, I think it is important to look at all relevant material no matter how old, just be aware that the research may have moved on or advanced, but for gaining a thorough understanding, we must consider all research.
Like the famous quote: "If I have seen further it is by standing on the shoulders of Giants"
We're not going to disregard the great work of Issac Newton.
If a particular person hopes to remain in academic field or a related profession, publishing research work is essential. Sooner is better, otherwise there is a possibility of getting your findings out of date.
It depends on the subject. Latest research and findings (maybe last 10 years) should always be included in any case study. However, the classical papers can never be neglected that provide the baseline information.
This is an interesting topic, some journals require using papers published in the last 5 years. While it may be important to include recently published articles in your research, I do not think specifying such a time limit is justifiable, since you may have many key relevant papers that may have been published well beyond such a time frame. I think papers should be included based on merit and relevance, and not date of publication.
