concerning bookcat's cataloguing of ace books - yes, it's a mess:
or possibly several superimposed messes:
ace - 1302 "bookcat items"
ace books - 191 items
ace charter - 11 items
ace fantasy books - 7 items
ace science fiction - 16 items
ace star - 4 items
charter - 22 items
charter communications, inc. - 3 items
sunridge press - 3 items, a charter communications imprint appears quite closely associated with ace
mason/charter - 2 items, may or may not be connected
charter uk - 1 item, rather murky background; may be an entirely illegal publication. it bears an 0-425- berkley block isbn, a uk price on the front cover, one copy only known, apparently, bought in texas.
(excluding ace books ltd. which was an unconnected uk publisher, and the ace/stoneshire imprint whose origins, existence and disappearance are, to put it mildly, shadowy - but appear to be british.)
(also excluding new infinities books, gary gygax's publishing co. whose mmpbs were distributed by ace / the berkley publishing group and bore 0-441- ace, ace charter, charter block isbns,
also excluding the iron crown tolkienquest/merpquest gamebooks distributed by ace/berkley,
and
definitely excluding prestige & ace/prestige titles, which are a whole other complication, being part of the extremely messy collapse and bankruptcy of lancer books and its aftermath.)
ace books, later the ace imprint, timeline:
1953 - 1969/70 ace books set up & owned by a. a. wynn, ace books inc.
1969/70 - ?1971? ace books, charter communications, inc. who also publish charter books, ace/charter books, and own other imprints and possibly also own other publishers.
charter communications, inc. run out of cash, and ran out of any credibility with authors and agents.
?1971? - 1983 publishers grosset & dunlap, inc. buy charter communications, inc. and ace books, possibly simultaneously (likeliest), eventually straighten out certain accounting problems that have come to light, turn it around, continue ace books as a profitable and properly-run publishers
1983 the berkley publishing group (or putnam-berkley publishing group) buy ace books or grosset & dunlap publishing including the ace imprint
1996 penguin or random penguin buy the putnam / berkley publishing group, including the ace imprint
2013 random house and penguin merge to become random penguin or similar, which since some time in 2020 has been wholly owned by the bertelsmann multinationalmegaconglomerate.

jimess: well spotted; as to the month of publication - that "may" should be "march" (source: jad smith's john brunner bibliography); correction submitted.
