As its name states, EETS was begun as a 'club', and it retains certain features of that even now. It has no physical location, or even office, no paid staff or editors, but books in the Original Series are published in the first place to satisfy subscriptions paid by individuals or institutions. This means that there is need for a regular sequence of new editions, normally one or two per year; achieving that sequence can pose problems for the Editorial Secretary, who may have too few or too many texts ready for publication at any one time. Details on a separate sheet explain how individual (but not institutional) members can choose to take certain back volumes in place of the newly published volumes against their subscriptions. On the same sheet are given details about the very advantageous discount available to individual members on all back numbers. In 1970 a Supplementary Series was begun, a series which only appears occasionally (it currently has 24 volumes within it); some of these are new editions of texts earlier appearing in the main series. Again these volumes are available at publication and later at a substantial discount to members. All these advantages can only be obtained through the Membership Secretary (the books are sent by post); they are not available through bookshops, and such bookstores as carry EETS books have only a very limited selection of the many published.
EETS was founded in 1864 by Frederick James Furnivall, with the help of Richard Morris, Walter Skeat, and others, to bring the mass of unprinted Early English literature within the reach of students. It was also intended to provide accurate texts from which the New (later Oxford) English Dictionary could quote; the ongoing work on the revision of that Dictionary is still heavily dependent on the Society's editions, as are the Middle English Dictionary and the Toronto Dictionary of Old English. In 1867 an Extra Series was started, intended to contain texts already printed but not in satisfactory or readily obtainable editions; this series was discontinued in 1921, and from then on all the Society's editions, apart from the handful in the Supplementary Series described above, were listed and numbered as part of the Original Series. In all the Society has now published some 475 volumes; all except for a very small number (mostly of editions superseded within the series) are available in print. The early history of the Society is only traceable in outline: no details about nineteenth-century membership are available, and the secretarial records of the early twentieth century were largely lost during the
