A number of questions will arise as you develop a research question. Has the question you are asking already been answered? Have other attempts been made to answer the question? If so, what techniques have been tried and what problems have arisen? Is there work in this area that will assist in developing your proposal? To find out you need to review the literature, that is, conduct a literature search. The idea of sitting in a medical library reading a few journal articles sounds interesting and easy. It is, but it is not a literature search. With so many medical journals published each year it is necessary to conduct a formal search of the published literature and the advent of electronic databases has simplified the process. However, there are a number of traps for beginners. As a beginner and having made most of the mistakes, I have been asked to write this article so that you can avoid the traps.
在你提出研究问题的过程中会出现许多问题。你所提出的问题是否已经有了答案？是否有其他人尝试过回答这个问题？如果是，他们尝试了哪些技术，又出现了哪些问题？该领域是否有有助于完善你的研究计划的相关研究？为了找到答案，你需要查阅文献，也就是进行文献检索。坐在医学图书馆阅读几本期刊文章，这个想法听起来既有趣又轻松。确实如此，但这并不是文献检索。由于每年出版的医学期刊众多，因此有必要对已发表的文献进行正式检索，而电子数据库的出现简化了这一过程。然而，对于初学者来说有许多陷阱。作为一个犯过大多数错误的初学者，我受邀撰写这篇文章，以便你能避开这些陷阱。
