I noticed only now that the entry bimodule is in bad shape and needs some attention. For the moment I have added here a mentioning of the 2-category of algebras, bimodules and intertwiners and a pointer to the Eilenberg-Watts theorem.

I quote from the current entry:

Remark 4.2. As this notation suggests, $BMod_R$ is naturally the vertical category of a pseudo double category whose horizontal composition is given by tensor product of bimodules. spring

Does anyone know what the ’spring’ is doing at the end or should it be deleted?

1. It’s a device Urs uses sometimes when editing, I think to remember where to begin again from after stopping. If it’s still there after some time, it can be deleted!

Right, sorry, thanks for catching. Have removed it now.
