Hello All - I'm trying to download a few thousand marc xml files from Internet Archives for out of copyright books. I'm following the url pattern described in the Instructions for contributing MARC records for Open Libraries <https://docs.google.com/document/d/1EnmeLTWhJMRpS860UMFkqCNzb-FEfiT8xFG8oXnAybk/edit#heading=h.fbdtjmsnogsi> -- https://archive.org/download/**iaidentifier*/*iaidentifier** _archive_marc.xml which works for a large portion of the titles, e.g. https://archive.org/download/ <https://archive.org/download/sacredgames00chan/sacredgames00chan_archive_marc.xml> scotlandantholog0000unse <https://archive.org/details/scotlandantholog0000unse>/ <https://archive.org/download/sacredgames00chan/sacredgames00chan_archive_marc.xml> scotlandantholog0000unse <https://archive.org/details/scotlandantholog0000unse>_archive_marc.xml <https://archive.org/download/sacredgames00chan/sacredgames00chan_archive_marc.xml> However, I am finding a significant proportion are giving me 404 errors. I suspect they are all for google books since the IA id ends in 'goog', e.g. https://archive.org/download/worksstephenoli00churgoog/worksstephenoli00churgoog_archive_marc.xml and https://archive.org/download/worldhereandthe00dickgoog/worldhereandthe00dickgoog_archive_marc.xml Does anyone have any experience with getting this or have any ideas as to how to get the marc records for titles such as these?
