Learning a Third of Further Language

There has been a lot of research on L1 and L2 acquisition, but research on learning third (or further) languages is a field of interest that received little attention before the 2000s (see Ulrike Jessner's review, below). In the scientific literature, this field is known as TLA: third language acquisition.
This page collects references to research on third or further languages, transfer (or interference) that may occur, and learning strategies for learners of further languages.
