Reference guide for APA 7th edition - Short version
Short version of the reference guide for APA 7th edition, a guide intended for students at the departments of Biology and Environmental Science at Lund University on how to format references according to the APA style.
References to two or more works by different authors in the same parenthetical citation are ordered alphabetically and separated using semicolons. When referring to several works by the same author in the same parenthetical citation, state the authors' surname(s) once and give only the date for subsequent work ordered by year of publication and separated using commas.
