I have started indexing on familysearch.org.
Indexing is converting written documents like birth certificates, censuses, military records, marriage certificates, death certificates, etc into digital format so that they can be found on the internet by geneologists and people searching for their ancestors.
I have wanted to do this for a while, and am so grateful that I finally have the time right now.
I started 3 days ago, and after spending a little time learning how to do it, and trying a few practice batches, I have indexed 5 batches of birth certificates from Manila, Philippines in the 1940s and 50s. Each batch has 15 records.
It is fascinating, and I love feeling like I am participating in a little bit of history.
If you are interested, you can go to familysearch.org and try some sample indexing.
All you need is a computer, access to the internet, and a little time.
