Your support files mention ISBNDB, but not accounts there. Assumedly the API key in the default install is one assigned to the program - is this limited? There is mention of limits in terms of Amazon and the like (understandable as their business is selling books), but not for ISBNDB (whose business, on the other hand, is supplying ISBNs)
I started off finding ISBNs, then suddenly noticed that the last 5 or 6 had not matched. I think this was a limitation of some sort, because I retried one that has previously matched and it failed. I have signed up for my own key - hopefully that will be less limiting. Perhaps info on this should be included somewhere in the help files.
However, my main worry here is that AEM did not tell me that a limit had been reached, it just failed to match ISBNs, when in fact there are matches in the database. That would seem to me to be a bug.
Hi, thanks for your help.
We will add this limit notification in the next version. Could you please specify the approximate number of requests that ISBNDB allows without limitations?
