This grand project requires mutual trust and a common understanding of how the community works.
What does that mean to you?
Some have told me that unless they can check my sources they would not trust my work, but what about sources that can not be verified? I have Death certificates for people that can not be found on line and state, on the document, that it is illegal for me to reproduce them. Others can not check them without spending hard earned money and proving that they are related so does that mean that they are not valid sources?
I am a volunteer for the familysearch indexing project and worked on the 1940 US census. You can see the result of my work and on that census and at least see the document but what about the index records that you could not see an image without paying another site? are you just going to write off the work of other hard working people just because you can not see the actual record yourself?
There are good works out there and bad works out there but unless you at least give those who post sources on here the benefit of doubt that they are working to provide accurate sources then you will be spinning your wheels trying to check out every source that others have provided.
I have added several sources that had names spelled differently and even dates that were off by several years, but rest assured that I have a very good reason for including them and it is not just because they "could" be correct. On those profiles I will eventually add my reasoning and will do that with any profiles I work on from now on, but it will take me a long time to go thru all the profiles on my watchlist.
