Some of you will already be aware of this very welcome service provided by the Oxfordshire Family History Society, but I thought I'd give it another plug.
You can send in transcriptions, and they are made available in indexed form.
You can easily search for other transcriptions too.

I have started sending in my transcriptions, and I have been very pleased that I have. If you send the copy of the document, the very helpful site coordinator checks it against your transcription and helps with any problems.
It must a labour of love, considering there are references to over 55,000 people.
