To know recent research works in neurosurgical fields and to analyze neurosurgery related sites on the internet, authors have been searching sites on the web offering the neurosurgical resources. From December 1995 to October 1996 we used a modem(28.8Kbps) and thereafter connected to a LAN(local area network). Under the environment of Windows 95, we used web browsers with Netscape 2.02 and Netterm 2.89. We got an medical information with PC journals or seminars and graded the neurosurgical center/institutes from A to E according to the quality of web sites. We could use the internet resources more rapidly in the early morning than noon or evening. Best sites for neurosurgeon were MedMark(http://www.medmark.bit.co.kr/neurosur.html) and Neurosource (http://www.neurosource.com/). The more comprehensive academic neurosurgical site among all web were the Massachusetts General Hospital(http://neurosurgery.mgh.harvard.edu/) and the University North California (http://sunsite.unc.edu/Neuro/uncns/home.html). In 89 neurosurgical center/institutes, 72 sites(80.9%) couldn't supply sufficient information. In conclusion, there are many webs related to neurosurgery on the internet, but useful sites for neurosurgeon are not common. It is necessary to make an effort to find available sites offering more information in the future.
