A (comparatively) long time ago our society produced printed publications of register transcriptions. Obviously the stocks that we hold go down over the years as items are sold. The source documents for many of these publications are now lost and so it would be very difficult to arrange a reprint, and even if we had the originals printing costs have risen and it might be uneconomic.
I’ve just completed scanning the Bishops’ Registers as they had gone out of print, and these are now available as PDFs on CD-ROM via GENfair here. Apart from keeping the information available there is an additional benefit for our customers in that we can make both publications available on a single disk at the same price that one of the printed books was sold for.
