The reason I asked that meta-tags be added to the newsletters was so that the reader could get more information about the story before he or she clicked any further. For many of the readers, it might be that they are looking for information on a specific company/client and finding that information listed as part of the synopsis of the story would influence their decision to click through and go to the actual story. The folks at InfoNgen added the feature to include selecting all or none of the meta-tags available, ranging from internal meta-tags that you've set up, to the basic company, industries, regions, countries, and states tags.
This is another nice feature to add to the product for a couple of reasons. First, it gives the end-user more flexibility in what types of alerts or newsletters they are receiving. Second, it helps promote the service that the library or marketing departments are offering in setting up current information awareness resources. To further this goal, I suggest that when you notify the end users that they can sign themselves up for newsletters or alerts, also let them know that if there is a topic that they do not see on the newsletter or alerts page, that one could be set up for them.
InfoNgen is a subscription based product, and we've talked about them and their competitors before. Whether you call them news aggregators, discovery engines, or listening platforms, these resources are extremely helpful in pushing current awareness information in front of your end users. Many law firms are evaluating these products and finding unique ways of setting up results ranging from broad topics down to individually specialized results, librarians and marketing teams are leveraging these tools to push current, relevant information to others within their firms or companies.
