Abstract: In 2006 the Space Telescope - European Coordinating Facility (ST-ECF), together with its partners at the STScI and the CADC, started a project to build a Hubble Legacy Archive (HLA): a collection of high-level Hubble data products and access tools to ease scientific analysis in the age of the Virtual Observatory. The ST-ECF has focused on providing extracted spectra from slitless spectroscopy HST images. The slitless NICMOS G141 data were presented at previous ADASS meetings and have already been released. In this contribution we present an overview of the ongoing project of processing the ACS/WFC G800L data which cover a larger area and contain more spectra. There are around 150 ACS/WFC G800L datasets covering an area of ~ 600 arcmin2, and we expect to extract and publish about 20,000 fullycalibrated spectra. We discuss the techniques and methods that were developed to automatically extract the spectra from the observations and present a selection of ACS/WFC G800L spectra as examples.
