I do a weekly list of items added to the collection for the Lunar and Planetary Institute. This week I've added a couple of COinS to the page. I've also suggested to my readers that I link to the Open WorldCat page if the item is not available on-line. No such items this week. I'm not sure if having links to Open WorkdCat and on-line versions of items may be confusing. Now when a user hits a link they know they are going to the item. In the future they may wind up at another service. Confusing? Time will tell.
