The only reason I can think of that the 1900 census is difficult to search would be for those of us who have Ancestry.com as our primary source of census images. The 1900 on Ancestry.com is images only, no index, so you have to know where they lived, and then you have to wade through the individual pages to find your query. It's pretty hard unless you know exactly the enumeration district or ward number. The "real" 1900 census itself is indexed and available on microfilm in many genealogical libraries. Constance
