(I heard that DAHR is integrating the Decca Labels Discography which
will help a lot)
In the mean time I would like to share that we have digitized the 6
volumes Decca Labels Discography and this morning I have used it to find
some of our missing dates in the Decca transfers in the Great 78 Project.
The most efficient way I have found is to search the PDF of the index
(vol 6) with the performer, then search the specific volume for the
catalog number, then record the date and location in the Internet
Archive item review with a link to the right page in the online version
(which you have to borrow to see).
If others would like access in some way please write to us.
