The Hubble Legacy Archive (HLA), developed jointly by the Space Telescope Science Institute (STScI), the Space Telescope - European Coordinating Facility (ST-ECF), and the Canadian Astronomy Data Centre (CADC), provides researchers with science-ready data products from the images and spectra obtained by the Hubble Space Telescope (HST). Users have access to both the standard archive images and spectra and a broad range of enhanced products, which, as of Data Release 3 (May 2009), include stacked ACS, WFPC2, and NICMOS images, extracted ACS and NICMOS grism spectra, and prototype mosaics combining several separate ACS visits into a single image. Color composites and a graphical search engine help users quickly identify the data they need, and source lists for almost all public WFPC2 and ACS data can be retrieved and overplotted onto the relevant images. The HLA also provides integrated access and search for high level science products, most of which are community-provided and include early observations with WFC3 and COS, the new instruments installed on HST during Servicing Mission 4 in May 2009. The HLA data are also used to verify the calibration and long-term stability of HST. A companion poster provides more details on the generation of the source lists and their properties. The HLA can be accessed at http://hla.stsci.edu.
