We announce the launch of grbcatalog.org, a web portal dedicated to Gamma Ray Burst (GRB) studies. Essentially, grbcatalog.org is a public web site maintained by GRB enthusiasts, which includes published information about all the GRBs detected thus far since its discovery in 1960s. The grbcatalog.org features web based data analysis tools that can be used by anyone with a web browser. These tools can create publication quality plots for GRB researches. In addition, grbcatalog.org also has a GRB News site (www.grbcatalog.org/news) to announce interesting events related to GRBs and Public GRB wiki (www.grbcatalog.org/wiki) that can be freely used by GRB researches to collaborate on GRB studies.
