Collectors who could not travel to London and other major cities where record fairs were being held, or the biggest record dealing shops were based, found themselves limited by their situation. The mail order listings in "Record Collector" were important, and one of the few places for buyers and sellers to make contact with each other. At its height, this section was up to half of the publication. However, at the turn of the 21st century with the success of selling to consumers on-line via sites such as eBay, many sellers now use this type of method and the amount of listings has greatly declined.
