The use of data from the Hubble Space Telescope (HST), and the number of refereed publications produced from this data, are now dominated by HST archival research. The Hubble Legacy Archive (HLA) is currently being constructed as a means of providing a heightened level of HST archival data to the astronomical community. We provide a general examination of the current strategy and the steps being taken to produce source lists for HST's Advanced Camera for Survey's (ACS) imaging data as a user resource to be included in Data Release 1 (DR1) of the HLA. We plan to provide both Source Extractor- and IRAF DAOPHOT-based source lists to facilitate the needs of the community in the identification of extended and point sources, respectively. These source lists will be created from drizzled, combined, and astrometrically corrected ACS images. The Early Data Release (EDR) at the end of July 2007 provided an initial set of test data for the public as a means of gaining user feedback. DR1 is currently planned for the end of January 2008, and will include a more extensive set of source lists than that of the EDR. An increased level of precision in source detection and refinement will provide the next generation of ACS data for use by the community. Additional future plans include the development of an "All-HST-Sky" source list that will include observations for the various HST instruments.
