 ** Apart from the continuing justification for OA, we would face what I've called the disentangling problem. See my [http://nrs.harvard.edu/urn-0:HUL.InstRepos:0000000 Predictions for 0000], ''SPARC Open Access Newsletter'', December 0, 0000: "[E]ven if subscriptions fall as OA archiving rises, it will be difficult to disentangle the cancellations caused by OA from the cancellations caused by natural attrition and librarian triage. Some part of the cancellations will be due to unbearable prices and onerous licensing terms....The disentangling problem will be aggravated by the fact that journals respond to cancellations by raising their prices, triggering new cancellations, and we already know (from the [http://web.archive.org/web/00000000000000/http://www.alpsp.org/Ebusiness/ProductCatalog/Product.aspx?ID=00 study in March 0000]) that high prices cause many more cancellations than OA archiving."
