COMMENTARY
For the last two years, Nucleic Acids Research has published a special issue devoted to web servers. This Web Server Issue highlights bioinformatics servers that are provided to the research community using internet technologies. This issue represents a rich repository of resources that are freely accessible, ready to use, and have been subjected to rigorous peer review. In the 2005 Web Server issue, there are 160 articles that describe the utility and functionality of 166 servers. The scope of the server applications described in this issue covers diverse ground and is hosted on servers in many different locations around the world. Among the tools included are those for text mining (1,2), sequence feature detection (3,4), predicting aspects of protein 3D structure (5,6) and performing expression analyses (7,8). Combined with the annual Database Issue (9), these special issues at Nucleic Acids Research represent a valuable directory of resources for the global life sciences research community.
Starting in 2005, Nucleic Acids Research has teamed with the UBC Bioinformatics Centre at the University of British Columbia (UBC) to ensure that all of the URLs and a short description from the Web Server Issue are listed in the Bioinformatics Links Directory, a curated listing of bioinformatics resources. The Bioinformatics Links Directory (http://bioinformatics.ubc.ca/resources/links_directory/) is a community resource that contains a directory of freely available tools, databases and resources for bioinformatics research organized within categories familiar to a biologist. All servers from the Web Server Issue, as well as other selected resources, are categorized within the directory. Table 1 displays a summary of web servers from this issue organized within the Bioinformatics Links Directory classification scheme. This scheme organizes links under 11 top level categories (DNA, Protein, RNA, Other Molecules, Expression, Sequence Comparison, Model Organisms, Human Genome, Education, Literature and Computer Related) to enable quick and easy access to listings of relevant servers. For an online version of this listing of the 2005 Nucleic Acids Research Web Server Issue servers, please see http://bioinformatics.ubc.ca/resources/links_directory/narweb2005/.
