+TABME was curated to promote research on page stream segmentation, a core task in automated document processing. 
+TABME++ improves upon TABME by adding higher-quality OCR annotations, but is still curated for the same purposes.

It was built to house and provide permanent access to tobacco industry internal corporate documents produced during litigation between US States and the seven major tobacco industry organizations and other sources. These internal documents give a view into the workings of one of the largest and most influential industries in the United States.
