London: The Fabian Society, 1884-1905. Thick octavo. Publisher's brown buckram, gilt; variously paginated, with individual titles ranging from 2pp to 50pp. Tight and straight, with scattered foxing to contents; Very Good.
The Society issued bound collections of its tracts more or less annually, compiling whichever titles were still in-print or on-hand as remainders. Contents of the annual volumes varied as remainders were depleted or titles went out of print or were withdrawn from circulation. As might be expected, the earliest tracts were the first to go, creating inevitable lacunae especially for the pre-1890 titles.
This is the compilation for 1905, including nos. 1 to 120, but with the following thirty-three tracts not included: 2-4; 6, 8-13; 15-18; 21; 25-26; 30; 33-36; 38-39; 43; 46; 52-53; 55; 60; 65-66; 77; 80; [87 present as a title page, in Welsh, only]; 106. Of the tracts present, the majority are the first printings, though a few of the more popular early tracts are present in later printings or editions (though none, obviously, later than 1905).
