Hello Bob,
Yes, there is a partial transcript of the Arlington parish registers which you can buy from:
http://www.ihgs.ac.uk/index.html , but it's on microfiche. If you go to the IHGS website click on "Library and Collections", then "Indexes & Collections", then "Sussex Collection.
The transcript covers:
Bapts 1607-1697 typed and 1699-1812 clearly written
Mars 1607-1695 typed, 1699-1753 clearly written and 1755-1837 typed
Burs 1607-1698 typed, 1700-1812 clearly written
Bishop's Transcripts 1606-1610
Index of Surnames 1606-1698
Index of Places 1606-1698
(Indexes say 1606 start, but it's actually 1607)
If you don't have a fiche reader you can always go along to your local library, or do as I did, and buy a second hand one on ebay - mine cost me £20 and a 50 mile round trip to collect, then a few months later £15 for a new bulb. I think you can also buy small hand held viewers.
Happy hunting,
Mandy
