There are two main academic papers presenting how Eora was constructed. The Supplementary Information for the "Mapping the Structure" paper contains a considerable amount of detail, including which data source(s) were used for building which IO tables.
Lenzen M, Kanemoto K; Moran D, and Geschke A (2012) Mapping the structure of the world economy. Environmental Science & Technology 46(15) pp 8374–8381. DOI: 10.1021/es300171x. Supplementary Information
Lenzen, M., Moran, D., Kanemoto, K., Geschke, A. (2013) Building Eora: A Global Multi-regional Input-Output Database at High Country and Sector Resolution. Economic Systems Research, 25:1, 20-49, DOI:10.1080/09535314.2013.769938
We also provide a document explaining the constrained optimization approach used to merge and reconcile multiple, often conflicting, data sources into a single balanced MRIO: EoraConfidence.pdf
On the horizon for development of future MRIO database is the Virtual Industrial Ecology Laboratory concept. This is a web-based platform where IO researchers from around the world can contribute and link IO data toward the construction of the next generation of global MRIO databases.

Several MRIO models exist. There is variation in the CBA results across models, but this variation is generally considered acceptable. For more on intercomparison see:
D. Moran, Wood, R. (2014) Convergence between the Eora, WIOD, EXIOBASE, and OpenEU's consumption-based carbon accounts. Economic Systems Research. DOI:10.1080/09535314.2014.935298

Another intercomparison website is the Environmental Footprints Explorer .
Below is a list of resources (papers, reports, and video) that can help in learning basic IO analysis.
The MRIO lecture video series by Prof. Lenzen is highly recommended if you are new to IO.
Most of the main papers presenting Eora and Eora-based results are provided above and in the individual applications sections (e.g. for carbon, water, and biodiversity footprints). We have also contributed to a number of additional papers related to the construction or use of MRIOs:
