I talked with some of my contacts at OCLC about your questions to make sure my thoughts were correct.

1. You can access xISSN from anywhere it isn’t limited to a particular IP range.

2. No, I don’t think the limit will be a problem because javascript is executed at the client side and the limits are from a particular IP, I believe. Xiaoming at OCLC said that “with Javascript callback, xISSN will see client-side IP addresses, right now OCLC has a 100 requests/IP/day limit by default and should be sufficient for most browser users. The 10,000 or other high volume usage are really targeting server-side processing.”

I’m not sure if I put the script on a server and access it via a script tag if this will cause the hits to all come from the server where the script is mounted. If it does and created a problem then I’d see if OCLC would increase our quota. I don’t think that they have a problem with increasing people’s quota, at least this is the impression I’ve been given. The limit is there so that OCLC can understand usage and if necessary throttle demand.

3. Adding the script to Serial solution is pretty easy. I’ll be posting directions shortly.

Great script! I was tinkering with it and it certainly does work as is!

However, there’s once piece I think other tinkerer’s may want to add to the xissn query if they are already a WorldCat affiliate:

url: “http://xissn.worldcat.org/webservices/xid/issn/”+ ISSN +”?method=getMetadata&format=json&fl=peerreview&callback=markPeerReview&ai=[youraffiliateloginIDhere]“,

I really dig it, although xISSN still blocks you with a “stat”:”overlimit” response after 100 requests without paying for more. The error doesn’t effect the load of the page itself, although there is some slowness in the script once that limit is hit. Haven’t quite figured out the solution yet, but working on it!

Cheers!

It works as it is. It just has to be put on a server and linked to in the Serial Solutions template. I’ll put up directions when I get a chance (which might not be soon I’m swamped).

Tried:
$(document).ready(function () {
getISSNs();
});

but it didn’t work.
Thanks!
Mike

Instead of

$(‘#CitationJournalIssnValue’).each(
function (i){
var ISSN = $(this).html();
$.ajax({
type: “GET”,
url: “http://xissn.worldcat.org/webservices/xid/issn/”+ ISSN +”?method=getMetadata&format=json&fl=peerreview&callback=markPeerReview2″,
dataType: “script”
});
}
);

function markPeerReview2(data){
if (data.group[0].list[0].peerreview == ‘Y’){
$(‘td #CitationJournalIssnValue’).append(‘ Peer Reviewed‘)
}
}

use

$(‘#CitationJournalIssnValue’).each(
function (i){
var ISSN = $(this).html();
var self = this; // capture this
$.getJSON( “http://xissn.worldcat.org/webservices/xid/issn/”+ ISSN +”?method=getMetadata&format=json&fl=peerreview&callback=markPeerReview2″,
function (data) {
if (data.group[0].list[0].peerreview == ‘Y’){
$(self).append(‘ Peer Reviewed‘)
});

});
