WormBase ( www.wormbase.org ) provides the nematode research community with a 
centralized database for information pertaining to nematode genes and genomes. 
As more nematode genome sequences are becoming available and as richer data sets 
are published, WormBase strives to maintain updated information, displays, and 
services to facilitate efficient access to and understanding of the knowledge 
generated by the published nematode genetics literature. This chapter aims to 
provide an explanation of how to use basic features of WormBase, new features, 
and some commonly used tools and data queries. Explanations of the curated data 
and step-by-step instructions of how to access the data via the WormBase website 
and available data mining tools are provided.
