These might be versions of the same site created in different times. Many Bank sites went through several redesigns and major updates. Web Archives tries to capture each new version of the same site throughout its lifetime. For example, you may be looking for a Nigeria country site. Instead, you may see two such sites available. It means that the site was redesigned or had a major update three times and we have a copy of each version of the Nigeria country site.
