Abstract
The Yohkoh Legacy Data Archive (YLA) is one of the first group of Resident Archives (RAs) selected for funding for NASA's Virtual Observatories for the Heliophysics Data program. YLA provides the best corrected data set of solar X-ray images and spectra from the Yohkoh satellite with a user-friendly web interface. As a RA, we take responsibility to keep our products well maintained and easily accessible. In addition, we have launched the 'E-consultant service', an e-mail based support to individual users regarding data handling to bolster access and use from a wide range of communities.
