With over a year since the launch of Google Scholar, I thought it was time to revisit my test of Google Scholar’s indexing of PubMed content. In my Sitelines article, Google Scholar is a Full Year Late Indexing PubMed Content of February 8 2005, I ran a test to see how GS’s coverage of PubMed stacked up. Using a randomly selected list of clinical trials on breast cancer (I wanted important articles that no physician would want to miss) spanning approximately 18 months of publication coverage, I discovered that GS was about one full year behind in coverage of PubMed….

Android Market is Google’s competitor to the Apple iPhone store

I was sent a link to the Android Community site this morning that led to the Android Developers blog post on the upcoming Android Market that looks to rival the Apple iPhone store for Android-powered devices. They decided to call it a market rather than a store to try to give it that "open" feeling for developers to provide content. There are several screenshots for you to check out too, including the one to the left. The Android Market will let users find, purchase, download and install content on their devices. The content does not appear to be screened by Google since you just need to register, upload and describe your content to get published. Hopefully it doesn't turn into a ...

Scratching Under the Surface of a “New” Health Search Engine

Lots of buzz this week about Healthline.com, a new vertical search engine for medical information. Chris Sherman, in his SearchDay review, quotes the company's promotional material, which indicates that the site covers "62,000 web sites with between 45-50 million pages... [and] hosted content licensed from reliable content providers." However, my own initial examination showed a site that offers little to rival the best quality ad-and-sponsorship-free medical content on the web through sites like Medline Plus. Healthline relies principally on content from popular pre-existing 3rd party .com sources that could be obtained from any commercial search engine. I conducted a search...

"Adding the infrastructure for canvas view gadgets allows users the choice of accessing more content directly from their gadget, which is part of this overall goal, and gives developers more space to create compelling gadgets. We've heard from both users and developers consistently that they want more gadget "real estate."Google is constantly thinking about ways to improve products for users, according to Ewing, who added that Google takes its ideas, prototypes them, and puts them through a vigorous set of usability tests to ensure they are the right move for users. "The iGoogle features we launched yesterday went through this exact process, and we've made changes along the way based on feedback from users and developers," he said.One of the biggest changes is with the layout and left navigation.Clicking any tab opens that tab, while clicking the plus sign next to any tab reveals a full list of the gadgets in that tab, according to Google. Viewing the tabs this way allows users to see all of a tab's content in one click. Mixed Reviews"We're excited about these changes because...
