The desired position of each illustration should be also marked in the typescript. The principal purpose of the list and reference style is to enable readers to locate cited literature. Acurate and complete references are therefore crucial. Misspelled names, incorrect dates, or missing publisher locations defeat the purpose of the list. When the author has any doubts, should include too much rather, than too little, information on the cited work.
All citations have to correspond entirely with the reference list.
All entries in the reference list must be cited in the text. The author should avoid to many citations. In the case of more than two authors, only the first name should be cited in the text with addition of the abbreviation et al. Personal communications, unpublished data, and manuscripts in preparation or submitted for publication should not be included in the reference list. In the text refer to them in parantheses by first initials and last name of source, type of material and date.
