                         persistent gravitational waves from continuous sources, e.g. 
                         rapidly rotating galactic neutron stars, and stochastic sources,

                         neutron stars. These searches can be degraded by the presence of 
                         narrow spectral artifacts (lines) due to instrumental or 
                         environmental disturbances. We describe a variety of methods used 
                         for finding, identifying and mitigating these artifacts, 
                         illustrated with particular examples. Results are provided in the 
                         form of lists of line artifacts that can safely be treated as 
                         non-astrophysical. Such lists are used to improve the efficiencies
