Reliable publications include established newspapers, academic journals and books, textbooks, and other published sources with reputations for accuracy and fact-checking.
Unreliable sources include blog posts and other self-published works, press releases, and social media posts.
In order for a source to be considered verifiable, other editors should be able to consult the source.
Is the source independent of the subject?
Is the source connected in any way to the subject? This is especially important when writing biographies or about organizations.
For example, if you were writing a biography, sources like the person's webpage or personal blog would not be considered independent.
Is the source primary or secondary?
Primary sources include first-hand accounts, autobiographies, and other original content.
Wikipedia allows limited use of primary sources, but typically only for straightforward, descriptive statements of facts, and only if they are published and verifiable without requiring specialized knowledge.
Secondary sources should be the main basis for a biography on Wikipedia.
If you're working on a topic related to medicine or psychology, ensure that your sources follow these special guidelines.
If you're creating a new article, consider the following:
Ensure that your topic meets Wikipedia's notability guidelines.
In order for a topic to meet the notability requirement, you must be able to identify 2-3 sources that are reliable, verifiable, and independent of the subject you're writing about.
Finding sufficient sources to establish notability can be especially hard when writing about people or organizations.
Sources that are not independent of the subject might be useful additions, but don't count towards the notability requirement.

This website is from ACS Publications and has high views and many citations with an orignal article issued in 1988 about the topic which should be a reliable source of information.
Hutchins, R. O., Hutchins, M. K., Crawley, M. L., Mercado-Marin, E. V., & Sarpong, R. (2016). Sodium cyanoborohydride. Encyclopedia of Reagents for Organic Synthesis, 1–14. https://doi.org/10.1002/047084289x.rs059.pub3
This citation is also from a trusted website with more than two writers and is a peer reviewed article which gives more reliable information about the topic and also has in depth characteristics about the topic in hand that will be useful.
This page is reliable due to many people controbuting into it as well as giving in depth information on how sodium cyanoborohydride reacts with other chemical compounds.
Examples:
Luke, Learie. 2007. Identity and secession in the Caribbean: Tobago versus Trinidad, 1889–1980 Kingston, Jamaica: University of the West Indies Press.
This is a book published by a university press, so it should be a reliable source. It also covers the topic in some depth, so it's helpful in establishing notability.
Galeano, Gloria; Bernal, Rodrigo (2013-11-08). "Sabinaria , a new genus of palms (Cryosophileae, Coryphoideae, Arecaceae) from the Colombia-Panama border". Phytotaxa.
This is a peer-reviewed scientific journal, so it should be a reliable source. It covers the topic in some depth, so it's helpful in establishing notability.
Baker, William J.; Dransfield, John (2016). "Beyond Genera Palmarum: progress and prospects in palm systematics". Botanical Journal of the Linnean Society.
This is a peer-reviewed scientific journal, so it should be a reliable source for a specific fact. Since it only dedicates a few sentences to the topic, it can't be used to establish notability.
Now that you have compiled a bibliography, it's time to plan out how you'll improve your assigned article.
In this section, write up a concise outline of how the sources you've identified will add relevant information to your chosen article. Be sure to discuss what content gap your additions tackle and how these additions will improve the article's quality.
Consider other changes you'll make to the article, including possible deletions of irrelevant, outdated, or incorrect information, restructuring of the article to improve its readability or any other change you plan on making. This is your chance to really think about how your proposed additions will improve your chosen article and to vet your sources even further.
Note: This is not a draft. This is an outline/plan where you can think about how the sources you've identified will fill in a content gap.
