The Internet as a new medium also has its use in medicine. Plenty of information which can be found on the world computer network, needs an efficient searching as well as an evaluation system and quoting of the information obtained. Twelve most popular search engines were chosen--9 general: Netscape, Altavista, HotBot, Goggle, Northern Light, Magellan, Infoseek, MSN; 2 specialized medical search engines: Medscape and Medline; and one Croatian search engine: Cross. The efficiency of searching was observed by analyzing the number of obtained pages, their contents and examples of the quoted references from the Internet. The searching was done using the mentioned search engines, and results varied from 2,189,793 network pages found on the Infoseek for the term 'skin cancer' to 0 pages with the search engine Cross for the term 'melanoma+therapy'. When comparing the results for a single term using various search engines, it is concluded that the number of pages varied because of different databases and specialized scooters that search and make indexes. It is possible to use logical operators and more advanced search systems with the majority of search engines. The quoting system is based on mentioning the names of the author and his work, the access date and url (uniform resource locator) addresses of the network pages. Permanent and reliable access to quotations could not be established with previous quotation systems. Dermatologic terms have been well dealt with concerning general population, whereas professionals are recommended to use Medline and reviewed web pages. There have been very few professional and professionally relevant and comprehensive pages on the Internet relative to the total of web pages.
互联网作为一种新媒体在医学领域也有其用途。在世界计算机网络上可以找到大量信息，这需要高效的搜索以及对所获信息的评估系统和引用。我们选择了12个最受欢迎的搜索引擎——9个通用搜索引擎：网景、阿尔塔维斯塔、HotBot、谷歌、北极光、麦哲伦、信息搜索、MSN；2个专业医学搜索引擎：医学景和医学在线；以及1个克罗地亚搜索引擎：Cross。通过分析所获网页数量、其内容以及来自互联网的引用参考文献示例来观察搜索效率。使用上述搜索引擎进行搜索，结果从在信息搜索上搜索“皮肤癌”一词找到的2,189,793个网页到在Cross搜索引擎上搜索“黑色素瘤+治疗”一词找到的0个网页不等。在使用不同搜索引擎比较单个术语的搜索结果时，可以得出结论，网页数量不同是因为数据库和进行搜索及编制索引的专业爬虫程序不同。大多数搜索引擎都可以使用逻辑运算符和更高级的搜索系统。引用系统基于提及作者姓名及其作品、访问日期以及网页的统一资源定位器（url）地址。以前的引用系统无法建立对引用内容的永久可靠访问。关于普通大众，皮肤病学术语得到了很好的处理，而建议专业人员使用医学在线和经过审核的网页。相对于网页总数而言，互联网上专业的、与专业相关且全面的网页非常少。
