The TNHJ Reference guidelines was sourced from the University of Queensland Australia Library resources, titled the “References/Bibliography Vancouver Style “How To guide”.
The list of references should contain details of only of those works cited in the text which preferably should not be more than 40 references. Your reference list should identify references cited (e.g., book, journal article, pamphlet, internet site, cassette tape or film) in sufficient detail so that others may locate and consult your references. Punctuation marks and spaces in the reference list and citations are very important. Follow the punctuation and spacing exactly in the examples given. When multiple references are cited at a given place in the text, use a hyphen to join the first and last numbers that are inclusive. Use commas (without spaces) to separate non inclusive numbers in a multiple citation e.g., 2,3,4,5,7,10 is abbreviated to (2-5,7,10) Do not use a hyphen if there are no citation numbers in between that support your statement e.g., 1-2. Give the first six names in full and add “et al”. The authors should be listed in the order in which they appear on the title page and ensure consistency in their referencing format.
You can use this list to carry out a final check of your submission before you send it to the journal for review. Please check the relevant section in this Guide for Authors for more details.
