Acknowledging that translation technology has brought about "fundamental changes and additional dimensions to all aspects of the contemporary world of translation" (p.xxxi), this encyclopaedia aims to serve as a key reference of fundamental concepts related to translation technology and of the research undertaken in this field.Given the fast pace at which technology evolves and the numerous developments involving the use of artificial intelligence (AI) in translation since the beginning of the 2020s, the publication of this second edition, which follows a first edition dating back to 2014, comes with updated content and five new chapters, making it therefore particularly relevant and topical.With a total of 47 chapters or entries, this collective volume is particularly welcome considering the scarcity of general and non-research focused monographs on translation technology.Austermhl (2001), Bowker (2002) and Quah (2006) became key reference works on translation technology in the 2000s and the early 2010s, yet we have had to wait until recently to read a similar publication, such as the textbook authored by Rothwell et al. (2023).Recent contributions of a more general nature are less generic and more focused on specific technologies, scenarios and types of translation (see, for example, Bolaos Garca-Escribano, 2025).Given that many of the aspects covered in works on translation technology will inevitably become dated, in current works the focus is often placed on key concepts and technologies, and how they have been implemented in representative tools (e.g.authors might choose a tool like memoQ to explore concepts related to translation memory (TM) tools).This is also the approach taken in Sin-wai's edited work, especially in Part 1, where general issues and topics within translation technology are discussed.While there is a strong emphasis on machine translation (MT) in this part, with 8 out of 15 chapters being devoted to this type of translation technology specifically, sizeable attention is also paid to the wider notion of computer-aided translation (CAT) and its training.Although at times it is not clear whether MT is seen as a type of CAT or rather as a technology that pursues full automation of the translation process, this part attempts to clarify the terminological confusion surrounding the very concept of CAT, including detailed definitions of key notions.Readers will also find compelling reflections on how the different types of translation technology and resources needed to operate these are related to each other.Some chapters delve into the concept
