Gollancz have published several series of reissues of fantasy, imaginative or just plain strange fiction over the years, including both A Voyage to Arcturus and The Haunted Woman. Here are lists of the series which include Lindsay's books.
This series of hardback reissues were brought out in 1947:
The blurb on the dustcover explained the aim of this hardback reissue series:
The word "rare", it should be explained, means that the books, long since out of print and eagerly sought after, have been practically unobtainable: as to "imaginative fiction" — well, perhaps "fantastica" (as the Times Literary Supplement headlined its review of the first three) would have been juster, but we were anxious to avoid any suggestion that the books in question were "fantasies". Anyhow, everyone likely to be interested in the series knew exactly what was intended.— from the dust jacket of The Haunted Woman Gollancz reissue 1964
The first five volumes of this series were brought out, in two batches, in 1963 (the first three being bound in red, all later volumes in blue), while the final three came out in 1964:
Number 5 in the series, although included on the series list page facing the title page of volumes #4 and #6 (it was The Greater Trumps by Charles Williams), was never released, and was not included in the series lists of the 1964 volumes. (Thanks to Paul Annis for this information.)
The 1978 reissue of A Voyage to Arcturus (in blue cloth boards, with gilt lettering on the spine, a silver dustjacket with blue lettering), was part of the Gollancz Fantasy Collection, an unnumbered series that included reissues, original novels, short story collections and anthologies. The reissues had metallic-coloured covers, but there was not the exact uniformity of look as with the yellow covers of the Rare Works of Imaginative Fiction series (though many were bound in black, and dustjacketed in black with yellow lettering & design). The books sported a Medusa's head logo, either in the "elongated" version (as pictured to the right), with the words Gollancz Fantasy & Macabre underneath, or a more rounded logo with the words Gollancz Fantasy or (as in the case of Philip Pullman's Galatea) merely Gollancz underneath it.
Here is a list of the works in this series, along with the dates when they were issued. Those marked with a † had Gollancz Fantasy & Macabre on their covers, as opposed to Gollancz Fantasy:

This series of paperback reissues was begun in 2000, and numbers 50 volumes as of 2007. A full list of titles can be found on the SF Site.
