Accordingly, it was recognized that work on a third edition would have to begin to rectify these problems. The first attempt to produce a new edition came with the "Oxford English Dictionary Additions Series," a new set of supplements to complement the "OED2" with the intention of producing a third edition from them. The previous supplements appeared in alphabetical installments, whereas the new series had a full A–Z range of entries within each individual volume, with a complete alphabetical index at the end of all words revised so far, each listed with the volume number which contained the revised entry.
