The Internet provides a quick access to a plethora of the medical literature, in the form of journals, databases, dictionaries, textbooks, indexes, and e-journals, thereby allowing access to more varied, individualized, and systematic educational opportunities. Web search engine is a tool designed to search for information on the World Wide Web, which may be in the form of web pages, images, information, and other types of files. Search engines for internet-based search of medical literature include Google, Google scholar, Yahoo search engine, etc., and databases include MEDLINE, PubMed, MEDLARS, etc. Commercial web resources (Medscape, MedConnect, MedicineNet) add to the list of resource databases providing some of their content for open access. Several web-libraries (Medical matrix, Emory libraries) have been developed as meta-sites, providing useful links to health resources globally. Availability of specific dermatology-related websites (DermIs, DermNet, and Genamics Jornalseek) is useful addition to the ever growing list of web-based resources. A researcher must keep in mind the strengths and limitations of a particular search engine/database while searching for a particular type of data. Knowledge about types of literature and levels of detail available, user interface, ease of access, reputable content, and period of time covered allow their optimal use and maximal utility in the field of medicine.
互联网提供了大量医学文献的快速访问途径，包括期刊、数据库、词典、教科书、索引和电子期刊等，从而为教育提供了更多样化、个性化和系统化的机会。网络搜索引擎是一种用于搜索万维网上信息的工具，这些信息可能以网页、图像、信息和其他类型的文件形式存在。互联网医学文献搜索的搜索引擎包括 Google、Google Scholar、Yahoo 搜索引擎等，数据库包括 MEDLINE、PubMed、MEDLARS 等。商业网络资源（如 Medscape、MedConnect、MedicineNet）增加了提供部分开放获取内容的资源数据库列表。一些网络图书馆（如 Medical matrix、Emory libraries）已开发为元站点，为全球的健康资源提供了有用的链接。特定的皮肤科相关网站（如 DermIs、DermNet 和 Genamics Jornalseek）的可用性是对不断增长的基于网络资源列表的有益补充。在搜索特定类型的数据时，研究人员必须牢记特定搜索引擎/数据库的优缺点。对文献类型和可用详细程度、用户界面、易用性、信誉内容以及涵盖时间段的了解，可以帮助他们在医学领域中最佳地使用和充分利用这些资源。
