I suspect the Thomson Reuter's font is custom, but would be excited to be able to license it for myself if it is available.
As for the font they have in their OneSource logo. This seems so very close to various fonts I already have but can't quite
nail it down as it seems the O has a bit more complexity and shape to it over a standard circle or ellipse, the S is very open
and the R is very geometric and wide compared to most fonts I looked that fit with the rest of the letter shapes.
