The creator of such indexes was expected to do their best not to omit pages, names, counties, etc. No one expected the indexer to correct misspelled names and erroneous birth dates and places. No one expected the index to be perfect. Genealogists must remember that the computerization of information does not inherently make it better. Computerized information is not infallible and believing that it is, has serious repercussions in areas besides genealogy.
Computerized information is easier to search and index, and on some levels easier to use.
However, information in digital format is not more likely to be correct than any other type of information. Computerizing information does not sanitize it, does not automatically scrutinize it, and does not make it infallible. Remember, nothing in life is one hundred percent accurate, just like nothing in life is fair. Okay, there you have it. I m not against technology, far from it.
