Gold/Diamond OA 2025: Gearing Up Part 2 « Walt at Random

"Finished subject analysis, which was faster than expected.

Also finished parsing APCs for the (first) currency and (first) amount, determining the set of currencies used, determining plausible conversion values for those currencies, and preparing the fee values.

Not including journals added or deleted after 12/14/2024, 7,342 of the journals have fees–and 1,621 of those have more than one currency. Using only the first currency encountered for each journal, there are 46 different currencies (including USD). For 31 of those currencies, I’m using OFX averages for the year through December 14. For another five (not in OFX), I’m using Xrates averages for the first 19 days of December. Finally, for ten other currencies, I’m using either Xe or MSN conversion rates for December 19.

The lowest fee, likely a conversion problem, is $0.0126 per article. Eight others show fees of less than $1, and all might be problems: I’m not in a position to judge. At the other extreme, sixteen journals have fees greater than $6,000 per article, with four of those above $7,000 and two at $8,900. (Both Elsevier.) ..."
