Top 4 Journals Classification Systems You Should Know
Dec 13, 2024 |
13 Mins ReadIf you’ve ever tried to figure out which journal is the best fit for your research or wondered how journals classification is carried out, you’ve probably come across terms like Quartiles, H-Index, Impact Factor (IF), and Source Normalised Impact per Paper (SNIP). These metrics might sound technical, but they are simply tools to measure how much attention a journal’s research gets. Here’s a straightforward explanation of what they mean and how they work
Quartiles in Journals Classification: Ranking by Performance
The system of dividing journals into four quartiles, Q1, Q2, Q3, and Q4, was created to make it easier to compare their quality and impact within a specific field. This idea became popular through Scopus and Journal Citation Reports (JCR) databases, which rank journals based on metrics like citations. The concept builds on the work of Eugene Garfield, who introduced the Impact Factor, offering a way to see how journals stand up against others. Quartiles break things down further: Q1 represents the top 25% of journals in a category, while Q4 includes those at the lower end. It's a straightforward way to help researchers determine which journals are most influential in their areas of study.
- Q1: Top 25% of journals in the field (highest-ranked).
- Q2: 25-50% (mid-high-ranked).
- Q3: 50-75% (mid-low-ranked).
- Q4: Bottom 25% (lowest-ranked).
However, not all Q3 or Q4 journals are necessarily a disadvantage. While they may not be as well-known, they are still important in scientific research. Some of the benefits include:
- Affordability: These journals are easier for researchers to access, especially for those on a tight budget.
- Focused Topics: They tend to cover more specific, niche areas of study, making them great for in-depth exploration of certain subjects.
- Great for New Researchers: Q3 and Q4 journals classification can be a good place for new researchers to publish their first paper and gain experience in the publishing world.
- Ideal for Basic Research: They’re a great option for research that focuses on the basics of science
Finally, publishing your article in a Q3 or Q4 journal doesn’t mean it lacks value or won’t make an impact. If your work presents new findings that address a real problem, it can still attract attention, even when published in a lower-ranked journal.
H-Index: A Balance of Quantity and Quality
The H-Index score is an important factor in journal classification. It looks at the number of articles a journal has published and how often those articles are cited. It balances quantity (how many articles a journal publishes) with quality (how many of its articles are referenced).
For example, if a journal has an H-Index of 15, it means it has published 15 articles, each cited at least 15 times. It’s a simple way to measure a journal’s influence without focusing too much on just one super-cited article or a bunch of rarely cited ones.
How H-index works:
Let’s say a journal has published 4 articles, and the number of citations for each article looks like this:
- The 1st article has 10 citations – exceeds 1 citation.
- The 2nd article has 24 citations – exceeds 2 citations.
- The 3rd article has 5 citations – exceeds 3 citations.
- The 4th article falls short of 4 citations.
In this case, the journal has three articles that each have at least three citations. The fourth article doesn’t hit the mark, so the H-index stops at 3.
This metric can help researchers, professionals, and institutions decide if a journal publishes research that gets noticed and cited by the academic community. It’s not the full picture, but it’s a useful starting point for understanding the journal’s influence.
Impact Factor: Citation Average
The Impact Factor (IF) is a number that shows how often a journal’s articles are cited on average over the past two years. It helps you understand how much attention the journal’s research gets from other scholars and it also helps with journals classification.
How it works?
To calculate the IF, look at how many times articles from a journal were cited in the past two years. Then, you divide that by the total number of articles the journal published in those two years. This gives you an average citation count per article.
Example:
Let’s say we want to figure out the IF for Journal A in 2023:
- In 2021 and 2022, Journal A published 50 articles.
- In 2023, those articles were cited 200 times in total.
- You take the total citations (200) and divide it by the total number of articles (50): 200 ÷ 50 = 4
So, Journal A has an Impact Factor of 4, meaning its articles were cited, on average, four times each. A higher Impact Factor often places journals higher in classification, but keep in mind that it’s not the full story. Some specialised journals may have lower Impact Factors even though they’re highly respected in their niche.
SNIP: Fair Comparisons Across Fields
SNIP (Source Normalised Impact per Paper) is a valuable metric in journals classification because it goes one step further. It measures contextual citation impact and takes into account the fact that different research fields have different citation habits. For instance, medical papers often get cited a lot, while mathematics papers don’t, even if they’re equally important in their fields.
SNIP adjusts the average citations a journal receives based on these differences, making it easier to compare journals across disciplines.
Example:
- Journal A publishes in a low-citation field like social sciences and averages 3 citations per article. Adjusted for its field, its SNIP might be 1.6.
- Journal B publishes in a high-citation field like biomedicine and has an average of 8 citations per article. After adjustment, its SNIP might be 1.2.
SNIP makes sure journals in fields with fewer citations still get the recognition they deserve.
What it tells you:
SNIP is especially useful for journal classification because it levels the playing field between disciplines. A higher SNIP score suggests that a journal’s articles are cited more often than expected for its field. It’s a helpful tool for comparing journals, but it’s just one of many ways to evaluate a journal’s influence or importance.
Conclusion
Metrics like Quartiles, H-Index, Impact Factor, and SNIP are essential tools for journals classification, helping researchers, librarians, and institutions rank journals and understand their influence. Each metric focuses on a different aspect of a journal’s impact.
But no single number can tell the whole story. A journal might excel in one metric but be less prominent in another, or it might be vital to a specific audience despite modest scores. These tools are helpful guides, but the best journal for your research depends on your goals.
Making Scholarly Research Accessible for Independent Researchers in 2025
Many researchers work outside of universities or formal institutions. These independent researchers often rely on public access to scholarly research to study, write, or contribute to their fields. However, access to scholarly research is not equal. Most academic journals are behind paywalls, which means users must pay to read them unless they are affiliated with an institution that pays for access. In this blog, we’ll explore the structure of academic publishing and how it affects independent researchers. We’ll break down the current challenges, the systems in place, and recent developments designed to improve research accessibility. Why Research Accessibility Matters Research accessibility refers to how easily someone can read, use, and build upon academic studies. For independent researchers, access is often limited because they lack university or library credentials required to unlock paywalled content. A large portion of scholarly research remains behind subscription paywalls. Many journal articles cost between $30 and $50 each, and full journal subscriptions can reach thousands of dollars per year. These costs create a divide between researchers affiliated with institutions and those working independently. Independent researchers may be excluded from current findings, which restricts their ability to contribute to academic conversations. Without equal access, knowledge development becomes uneven. Some communities and individuals are left out, creating a gap in who can participate in scientific and scholarly work. Understanding Open Access Models Open access (OA) refers to academic research that anyone can read online without paying. There are different types of open access, and each works in a specific way. 1. Gold Open Access to Scholarly Research Gold open access means that the final version of a research article is freely available on the publisher's website. The author or their funder usually pays a fee to make the article open. Researchers can find gold open access content in fully open access journals listed in the Directory of Open Access Journals (DOAJ). These journals allow anyone to read and download the scholarly research directly from the publisher. Reader benefit: Immediate access to the final, formatted version of articles Limitation: Authors often pay fees ranging from $500-$3000 to publish 2. Green Open Access Green open access is when authors share a version of their article in a free online repository. This version may be a preprint (before peer review) or a postprint (after peer review but before journal formatting). Repositories like arXiv.org specialise in many disciplines, and bioRxiv.org for biology, host these papers. These platforms do not require any affiliation to access the content. Reader benefit: Free access to research content, often before formal publication Limitation: The version available might not be the final published version 3. Diamond Open Access Diamond open access journals make articles freely available to read and do not charge authors any fees to publish. Neither readers nor authors pay. One good example of diamond open access is KnE Publishing, an open access publishing service by Knowledge E, provides high-quality publishing services to support the development and advancement of diamond open access journals, with a particular focus on increasing the visibility and accessibility of scholarly research. This model is often supported by academic institutions or non-profit organisations. The Free Journal Network lists many of these journals. Reader benefit: Completely free access with no barriers Author benefit: No publication fees to share research Open Access ModelWho PaysWhere to FindVersion AvailableGoldAuthors/fundersPublisher websitesFinal published versionGreenNo one (usually)RepositoriesPreprint or postprintDiamondInstitutions/grantsPublisher websitesFinal published version Practical Tools For Independent Researchers Independent researchers need affordable ways to find and use scholarly research. Several tools make this process easier. AI Summarisers AI summarisers extract the main points from academic papers. These AI tools help researchers quickly understand if a paper is relevant to their work without reading the entire document. Zendy's AI summarisation tool identifies key findings, methods, and conclusions from scholarly research papers. This saves time when reviewing large amounts of literature. Time-saving: Condenses hours of reading into minutes Comprehension aid: Helps readers understand complex academic language Literature Discovery Tools Discovery tools help researchers find academic papers and locate free versions when available. Google Scholar indexes scholarly research and sometimes links to free versions. Zendy uses AI to recommend relevant papers based on your interests. Browser extensions like Unpaywall and Open Access Button automatically find legal, free versions of paywalled articles. Broader search: Searches across multiple journals and repositories at once Free alternatives: Identifies open access versions of paywalled content Scholarly Research Reference Manager Tools Reference manager tools help organise research papers and create citations. These tools are essential for independent researchers writing their own papers. Zotero is a free, open-source reference manager that saves papers, creates citations, and integrates with word processors. Mendeley offers similar features with some social networking elements. Organisation: Keeps research papers in one searchable library Citation help: Automatically formats citations in different styles Policy Shifts Empowering Independent Scholars Recent policy changes are increasing the amount of research that is freely available to everyone. These changes help independent researchers access more content without institutional subscriptions. Plan S requires that research funded by certain organisations be published with open access. This means more high-quality scholarly research is becoming freely available to read. Many funding agencies now require researchers to share their findings openly. The National Institutes of Health in the US and UK Research and Innovation have policies requiring funded research to be publicly accessible. Authors are also finding ways to keep their rights to share their work. Rights retention strategies allow researchers to post copies of their articles in public repositories even when publishing in traditional journals. The trend toward open science continues to grow. More institutions are adopting policies that make research outputs—including data, software, and educational materials—freely available by default. Ensuring Accessibility For All Researchers Accessibility in scholarly research goes beyond open access. It also means making content usable for people with disabilities and those using different devices or internet connections. Universal Design Principles Universal design makes scholarly research usable by as many people as possible. This includes clear structure, readable text, and compatibility with assistive tools. Well-designed articles use proper headings, include descriptions for images, and create documents that work with screen readers. These features help all users navigate and understand the content more easily. Examples of accessible design in scholarly research: Structured headings that create a logical outline Alternative text for images and diagrams Tables with proper headers and simple layouts PDF files with proper tagging for screen readers Assistive Technology Compatibility Assistive technologies help people with disabilities access digital content. Researchers need to work well with these tools. Screen readers convert text to speech for people who are blind or have low vision. Text enlargement tools and colour contrast adjusters help people with different visual needs. When looking for accessible research content: PDF accessibility: Look for tagged PDFs that work with screen readers HTML versions: Often more accessible than PDFs for assistive technologies Plain text options: Simple format that works with most assistive tools If you need a more accessible version of any scholarly research, you can contact the publisher directly. Many journals now provide alternative formats upon request. New Innovations in Research Access The landscape of scholarly access continues to evolve with new models and technologies making research more available to independent scholars. AI-powered research assistants are changing how people interact with academic literature. These tools can summarise articles, extract key information, and help researchers find connections between papers. Digital libraries like Zendy are creating alternatives to traditional subscription models. With AI assistants like ZAIA (Zendy's AI assistant for researchers), these platforms not only partner with publishers to offer access to both open and paywalled content at affordable rates for individual researchers, but also enhance the research experience through AI support. The future of scholarly research access looks increasingly open and innovative. New technologies and business models continue to break down barriers between knowledge and those who seek it. FAQs about Accessing Scholarly Research How can independent researchers find free academic articles legally? Independent researchers can use open access repositories like PubMed Central and preprint servers like arXiv. Public libraries sometimes offer access to academic databases, and contacting authors directly often results in them sharing their papers. What makes scholarly research accessible to people with disabilities? Accessible scholarly research uses proper document structure with headings, provides alternative text for images, creates tables that screen readers can navigate, and offers formats compatible with assistive technologies. Articles in HTML format are typically more accessible than PDFs, and properly tagged PDFs are more accessible than untagged ones. How do researchers evaluate the quality of open access journals? Researchers can check if an open access journal is listed in the Directory of Open Access Journals (DOAJ), look for clear peer review policies, verify the journal's impact factor, and research the editorial board members. Quality open access journals maintain the same rigorous standards as traditional subscription journals. What AI tool helps independent researchers conduct a literature review? ZAIA, Zendy's AI research assistant, helps independent researchers conduct efficient literature reviews by automatically summarising academic papers, extracting key findings, and identifying connections between related studies. Researchers can also use reference managers like Zotero or Mendeley to organise papers and create citations. Literature mapping tools like VOSviewer help visualise research networks and identify influential papers. For comprehensive literature reviews, ZAIA can recommend relevant papers based on your research interests, saving hours of manual searching across multiple databases. .wp-block-image img { max-width: 85% !important; margin-left: auto !important; margin-right: auto !important; }

How to Write a Strong Literature Review (With Examples)
In a previous blog, we highlighted top 5 best AI tools for literature review that offer a large collection of research materials to support your research. Now, in this blog, we will go through the process and the 3 pillars of writing lit review while providing a real-life literature review example to help you grasp the concept with ease. What's a Literature Review? A literature review is a summary of what other researchers have already discovered about your topic. It helps you figure out what's already known, what questions still need answers, and how your own research fits into the bigger picture. What Are the 3 Pillars of Literature Review? Introduction The introduction of a literature review should: Provide context for the topic Define the scope and purpose of the review Outline the organisational framework Present a clear thesis statement Body The body of the literature review is where you analyse and synthesise existing research. Consider organising your review by: Themes or concepts Chronological order Methodological approaches Conclusion A strong conclusion should: Summarise key findings Highlight contributions to the field Discuss implications and applications Suggest directions for future research Tips on How to Write a Great Literature Review Read widely to get a full picture of your topic. Don't just summarise - analyse and compare different studies. Look for patterns and gaps in the research. Keep your writing clear and logical. Use transition words to help your ideas flow smoothly. How Zendy Can Help with Your Literature Review In order to write a strong literature review you need to find the right sources, and of course a tools to help accelerate the process. Zendy.io isn’t just a digital library that offers access to relevant studies across disciplines, but it also helps you write a solid literature review, Zendy AI tools include features designed to help you with literature reviews.

Real-Life Literature Review Example This is my favourite example of a literature review! Assume you're reviewing literature on climate change and agriculture: "Researchers have been studying how climate change affects farming for decades. Early studies in the 1990s focused mainly on crop yields (Stephen, 1992; Iana, 1995). As time went on, scientists started looking at more complex issues. For example, Sleman (2005) examined how changing rainfall patterns affect soil quality, while Monica (2010) investigated the spread of new crop diseases in warmer temperatures. Recent research has taken a broader view. Emad (2018) looked at how climate change impacts entire food systems, from farm to table. Meanwhile, Rodrigo (2020) explored how small-scale farmers in developing countries are adapting to new weather patterns. Despite all this research, we still don't know enough about how climate change will affect food security in specific regions. Future studies could focus on creating detailed, local predictions to help farmers prepare for what's ahead." See how this example of literature review flows naturally from one idea to the next? It gives you a clear picture of how research in this area has evolved over time. Other Examples of Literature Review Chronological literature review example: Learners’ Listening Comprehension Difficulties in English Language Learning: A Literature Review Methodological literature review example: Literature review as a research methodology: An overview and guidelines Theoretical literature review example: Why Do People Migrate?
