On Sunday, September 18 there will be a scheduled service downtime for the WorldCat Search API and WorldCat Basic API service from 1:00 a.m.
until at least 8:00 a.m. Eastern time (-4 GMT). This temporary service interruption is required so we can upgrade software that supports the WorldCat API.
We endeavor to have as little downtime as possible; this downtime is necessary.
