How do self-citations affect impact factor?

Self-citations can inflate a journal's Impact Factor (IF) by increasing the numerator (total citations) without necessarily reflecting genuine external interest, especially when excessive or manipulative, though top journals often have lower self-citation rates than lower-tier ones, showing a complex relationship where some self-citation is normal for relevance, but "citation stacking" (mutual self-citation among a small group) artificially boosts scores. While high-impact journals self-cite more frequently in absolute terms to their own recent content, lower-impact journals often have higher rates of self-citation relative to their total citations, creating an artificial inflation, notes this study.

How is CiteScore related to impact factor?

A primary difference between these two metrics is the period of time for the calculation; while the Journal Impact Factor calculates the metric using the two previous years as a basis for the citation count, CiteScore uses a three-year period.

Is 2.5 a good impact factor for a journal?

Yes, an impact factor (IF) of 2.5 is generally considered good quality for a journal, placing it above average (most journals have IFs below 2), but not in the elite, top-tier range (which often starts at 5+ or 10+). It signifies decent visibility and citation frequency, but its "goodness" highly depends on the specific academic field, as citation patterns vary significantly between disciplines. 

What is the rate of self-citation for journals?

Journals ranking in the top quartile of the category have self-citation rates of 10% or less. Journals in the lowest quartile show a greater diversity of self-citation rates, with values ranging from zero, to nearly 40 percent.

Is 3.7 a high impact factor?

Yes, a 3.7 impact factor is generally considered a good to very good score, representing a reputable journal, though "high" depends heavily on the specific academic field; it's well above the < 1 average and strong in many areas like social sciences, but might be considered moderate in extremely competitive fields like top-tier medicine where factors above 10 are common. 

Journal Impact Factors: What You Need to Know

Is 8.5 a good impact factor?

Impact Factor Range

Between 3 and 10 - Good to very good, depending on the specific field. Between 1 and 3 - Average but respectable in many fields. Below 1 - Generally low but acceptable for niche or emerging fields.

Can impact factor be manipulated?

However, impact factors may be manipulated by editors. According to the ex- planatory statements and announcements made by the authors submitting their work to the journals, the impact factor is still being di- rectly manipulated [4–6].

Which is better, Elsevier or Springer?

Elsevier, Springer Nature, and others are giant academic publishers, with Elsevier known for broad, high-impact journals like The Lancet and strong citation metrics, while Springer Nature (formed from Springer Science & Business Media and Macmillan) excels in STEM with its Nature brand and extensive Open Access (OA) options, both publishing vast collections of journals, books, and databases, with key differences lying in specific journal focus, editorial policies (like AI usage), and author-reader accessibility. 

How many papers get 1000 citations?

Most-cited papers

The 10 most cited papers all had more than 40,000 citations. To reach the top-100 papers required 12,119 citations by 2014. Of Thomson Reuter's Web of Science database with more than 58 million items only 14,499 papers (~0.026%) had more than 1,000 citations in 2014.

Does Google Scholar count self-citations?

If you still want to check the number of self-citations in Google Scholar, you can easily do so by double-clicking on the citations in question. I have provided an example below for a colleague, who understandably given her very recent publication history had a relatively modest number of citations (see screenshot).

What is Q1, Q2, Q3, Q4 journal impact factor?

Is an impact score of 30 good?

Impact scores run from 10 to 90, where 10 is best. Generally speaking, impact/priority scores of 10 to 30 are most likely to be funded; scores between 31 and 45 might be funded; scores greater than 46 are rarely funded.

What is considered a good CiteScore for a journal?

Do Scopus indexed journals have impact factors?

Although the journal indicators provided by Scopus are not used as often as the more established one by Web of Science, the Journal Impact Factor (JIF), you can use them as complementary tools when selecting journals. One obvious reason is that Scopus covers journals that are not indexed in Web of Science.

Is 40 references too much for a 3000 word essay?

What is the 3 paper rule?

The "3 paper rule" primarily refers to a modern PhD dissertation format where a thesis is structured as three standalone, publishable journal articles connected by an introduction and conclusion, forming a cohesive body of work. It can also refer to general writing/design principles, like the "Rule of Three" for structure (introduction, body, conclusion), the "Rule of Thirds"" in visual design for composition, or a "three-pass reading method"" for deep comprehension. 

Is 4.8 a good impact factor?

Yes, a 4.8 impact factor is generally considered very good to excellent, especially as it's well above the typical average (often under 1) and falls into the "good" (around 3) to "very good/excellent" (5+) range for many fields, though its true value depends heavily on the specific academic discipline. It signifies strong visibility and citation rates, but you should always compare it to other journals in the same subject category (quartile/percentile) for the best evaluation. 

What is the Elsevier controversy?

<<!Elsevier controversies>> center on its high journal prices (creating "double-dipping" for publicly funded research), restrictive author/sharing policies, and ethical concerns about its data services for fossil fuel companies, sparking researcher boycotts, mass resignations from editorial boards, and calls for greater open access, notably led by initiatives like The Cost of Knowledge and university contract cancellations, such as by the <<!University of California system (UC) https://www.universityofcalifornia.edu/press-room/uc-terminates-subscriptions-worlds-largest-scientific-publisher-push-open-access}>>.
