Many scholarly articles are becoming available on the Internet through preprint or e-print servers. Preprints are articles and manuscripts that have not yet been published. They have generally been reviewed and accepted for publication, submitted for publication, but not yet received a publication decision. Preprints and e-print server resources are a fast and inexpensive means of scholarly communication that allow other scholars to have near immediate access to the latest research. With the ease of publishing on the web, preprints are rapidly increasing in popularity in academia.
The best compilation of worldwide mathematics preprint and e-print sources is the AMS Directory of Mathematics Preprint and e-Print Servers, shown below. The umbrella servers provide access to the most substantial collections of preprints and e-prints in mathematics.
