Introduction
Human Papillomavirus (HPV) is the most common Sexually Transmitted Infections. Over 100 types of HPV have been identified. Some types of HPV cause genital warts, whereas other types cause cervical cancer or other genital cancers. Our purpose was to study the HPV research performance based on 12,692 documents published in Science Citation Index (SCI)-indexed periodicals between 1991 and These documents were analyzed and evaluated according to publication distribution and were used to determine the quantitative characteristics of the research.

Methods
Documents used in this study were based on the databases of the SCI which was accessed from the ISI Web of Science, ‘Human Papillomavirus’, ‘Human Papilloma Virus’ and ‘Papilloma*’ were used as keywords to search titles, abstracts, and keywords. Parameters analyzed included type of document, page count, authorship, journal, author keywords and country of publication.
Results
There was logarithmic relation between yearly cumulative number of publications and the year from 1991 to 2005.

Of the 10,248 articles in SCI, 5,570 articles had author keyword information. Among 25,625 keywords, 6,060 (24%) keywords were used only 1 time.
Conclusions
The logarithmic relation shows that HPV research was a constant growth rate on publications in the fifty year.
Twelve document types were found in the total of 12,692 documents. Eighty-one percent of all documents are articles.
As the keywords analysis, “Human Papillomavirus” is more popular than “Human Papilloma Virus”.
All articles were published in the total of 944 journals. Seventeen percent of all articles were published in journals which listed in the category of Oncology.
The G7 industrial countries (U.S.A., Japan, Germany, U.K., France, Italy, and Canada) represent a share of corresponding authors of 80% of world articles.
