Abstract:	Following a surge in the 1970s of research on the role played by the L1 in L2 acquisition, Ellis (1985) compiled ESL studies in which the percentage of L1-based errors was provided. He concluded that, according to available research findings, approximately one third of ESL errors appear to be due to L1 influence. For more than 30 years, that figure of 33% has been extensively cited, and Ellis’ table and/or its content has been reproduced in many publications. Increased accessibility to publications in electronic form makes it possible not only to add new studies to the table created by Ellis, but to make changes to the already existing table by adding studies conducted prior to 1985. A thorough search based on various selection criteria allowed us to greatly expand the original table with 20 newer studies, and eight studies that had been overlooked in 1985. We obtained the more reliable figure of 42%, based on 34 studies rather than on seven only.
