Do you have some inroads with 'management' that corrections would actually be processed and available online?
I'm a database guy so pardon the tech speak. What's needed is a second field for searching......one is the 'transcribed' version.....it's the best guess of what was printed.....this is mistakes and all...if the last name is Smythe and it looks like Smith then that's the value. Zamp in my case.
The second value is based on heuristics and local knowledge.....this is Samp in my case.
If the census taker made an error.....you need to keep that spelling intact...... what the correction column/field is is another search key to finding the record digitally......
Corrections in the past sent to numerous organizations have gotten nowhere.....so unless you have an 'in' this is a futile mission: proof reading the already 'proof read' transcription of a census takers penmanship of what he thought he heard in June 1900.
