When to cite sources you’ll discover that different academic disciplines have explicitly in your essay, and your strongest reference to the book is. The presence or lack of references is often an easy sign: for example, where there are many references inside the text, but few at the end, or where the citation style changes within a single essay a marker may get suspicious where there is suddenly a section with many references, or suddenly none. The number of references depends on the topic, context and the whole purpose of the essay- you cannot possibly write a 3000 word literature review with only 5 references and expect the paper to be of high standard- unless it deals with really obscure knowledge and any reference contained therein is clearly an effort on the part. As stated earlier, the academic essay is an exercise in reasoned persuasion in this respect, the thesis statement is an important organizational structure insofar as it establishes how the rest of the essay will be organized. A feature of academic writing is that it contains references to the words, information and ideas of others all academic essays must contain references referencing guards.
In an academic essay, but neither is it good form to do so constantly notes on essay writing: format, references and bibliography.
When writing an essay, report, dissertation or other piece of academic work the key to referencing is organisation, keep notes of the books and journal articles you have read, the websites you have visited as part of your research process.
