:: I attended a session at SLA in Toronto called The Future of Search Engines. One of the speakers was Cathy Gordon, Director of Business Development for Google. After stating that her opinions were her own, and didn't reflect those of Google, she began with a mini infomercial (standard fare, and expected) about the infamous search engine, noting that users can now search in >100 languages, it is the #1 search engine in 17 of 20 countries (didn't say which 17 countries, or the names of the other 3), and that Google powers 70% of all Internet searches. Google doesn't create its own content, tries to knock down spam results, and does not accept payment for inclusion. Users may submit web pages to Google for indexing, and currently it indexes >8 billion pages, and >12,000 news sources.
She mentioned "Premium Content" (apparently a new or forthcoming feature in which Google will somehow get behind subscription firewalls to for-fee dbs), and noted that book search results from Google Print are not integrated into Google web searches, as the pages from the books are not ranked.
In discussing Google Scholar, she said it was created by an engineer looking for scholarly content. Some dbs and full-text scholarly journals are being indexed, along with theses, dissertations, books, technical reports, and other material. When asked about a source list of what is indexed in Google Scholar, she said she didn't know exactly why this still isn't being offered by Google. GS uses link resolvers to allow for access to articles on an IP-authenticated machine (where the institution subscribes to the publication in which the article is found).
As for the topic of the session itself, Gordon believes that users will continue to demand more control, while the search engine will become more personal and sophisticated but must remain simple to use. The depth, breadth and type of searchable content will continue to expand, and the challenge is to present this variety of information in a coherent and cohesive manner. Geographic and language barriers will continue to decrease, and desktop tethering will be eliminated - i.e., the need to have a desktop computer to search will no longer be the case as searching becomes ubiquitious. To this end, Google offers the option of personalizing your Google homepage, along with My Search History.
She summarized as follows: searching remains a primitive function, users must be at the centre of improvements, the increasing amounts of searchable information will require innovative solutions to manage its complexity, and searching must be accessible at any time, from any location, using any device.
