Beginning with issue #326, the series began reprinting the Legion of Super-Heroes (1984) series as part of DC's "hardcover/softcover" trial. The new Legion series was to be released solely through the direct market while the "Tales" series would continue to be released through both the direct and newsstand markets. This format was designed to emulate the mainstream book market where a book would be released in hardcover with a paperback (or softcover) release coming about a year later. In this case, the higher-priced direct market edition was the "hardcover" and the lower-priced newsstand edition was the "paperback."
Most specialty comics stores quit ordering the Tales series after #325.
