The 29th AESLA Conference was held on the 4-6 May 2011, under the title Empiricism and analytical tools for 21st Century Applied Linguistics. Its objective was to offer a venue for researchers in several fields of Applied Linguistics to debate on theoretical, methodological, empirical and analytical aspects as regards language description. In this edition the main focus was to combine the empirical methodology of Discourse Analysis approaches with the critical perspective of the construction of social reality through language, with special reference to the use of new technologies applied to linguistic description and language teaching. The Conference welcomed as plenary speakers Professors Henry Widdowson (University of Vienna), Ana Mauranen (University of Helsinki), Michael ODonnell (Autonomous University, Madrid) and Pamela Faber (University of Granada). A Language Learning Roundtable Conference was also held, funded by the journal Language Learning, under the theme Corpus Linguistics for 21st Century Language Learning. Communications, roundtables and posters gathered in the Proceedings were organised, as in previous AESLA Conferences, in ten thematic panels representing the different sub-areas of Applied Linguistics and corresponding to the ten research areas in which AESLA is itself organised: Acquisition and learning Corpus linguistics, computational and language engineering Discourse analysis Language for specific purposes Language psychology, children language and psycholinguistics Language teaching and syllabus design Lexicology and lexicography Pragmatics Sociolinguistics Translation and interpretation The Conference in Numbers The total number of participants was 333, including Plenary Speakers, members of the AESLA Board and Panel Conveners.

Language Learning Roundtable Under the auspices of the Chicago-based journal Language Learning, a special roundtable was held on May 4th, CORPUS LINGUISTICS FOR 21ST LANGUAGE LEARNING.
