I'm pretty sure that the data available from
https://data.mtgox.com/api/2/BTCUSD/money/depth/full is the entirety of MtGox's depth data, and you can probably then filter it for 2013. Unfortunately, as I don't really know how the data is generated, I can't give any more information than that. Be careful with this resource, though - there is a download limit of 5/hour, which if you exceed may result in you being blocked from the API.
