What are we trying to accomplish?“We offer a fragmented set of systems to search for published information . . . each with very different tools for identifying and obtaining materials. For the user, these distinctions are arbitrary.” – UC Bib Serv Taskforce
Overview of the literature1990-1999“Is There a Chance for a Standardized User Interface?” –Fletcher2000-2004“Trumping Google? . . .” –Luther“Talking about a Revolution? . . . ” –Nicholas“The Answer to all of our Problems? . . .” –Groenewegen“The Right Solution . . .”  –Tennant
Overview of the literature2004-2008“Is Metasearching Dead?” –Tennant“Metasearching: Not as Good as We'd Like It” –NLAQ“Why Librarians Hate Metasearch” –McHale“Plotting a New Course for Metasearch” –Breeding
Arguing about metasearch“[C]ross-database search tools . . . are the correct solution for unifying access to a variety of information resources.” –Roy Tennant“Metasearching, then, is a step backward, a way of avoiding the learning process.” – William Frost“[M]etasearch … cannot stand up to search systems based on centralized indexes” –Marshall Breeding“Part of me keeps hoping [metasearch] will go away, but nope, it's still there.” – Andrew Pace
Arguing about metasearchBroadcast argument (pro)“You can search multiple databases simultaneously!”Nativist argument (anti)“The search is not advanced enough!”Immature technology argument (anti)“The search is too slow!”“Google Scholar is faster!”
Isn’t it ironic?Some librarians dislike metasearch because it is too much like Google; othersbecause it is not enough like Google.

Usability studies70% of the students in BYU study preferred metasearch over native interfaces“[B]oth [metasearch and searching native interfaces individually] produce citation sets of similar quality” – BYU “Graduate students and faculty . . . all located citations they had not previously found” 						–Texas A&M
On search times“Eight [out of 18] students measured the speed of the search processing as reasonable and only five found the system too slow.” –Maryland“Users are willing to wait as long as they think that they will get useful results. Their perceptions of time depend on this belief.”  –Santa Cruz“When people accomplish what they set out to do on a site, they perceive that site to be fast . . . If people can't find what they want on a site, they will regard the site as a waste of time (and slow).” – Perfetti, Landesman
On the interface“I found that both were not very user friendly.” – BYU  Student“[Non-federated search] lent itself to more abstracts . . . With [federated search] I was relying more on the title which can sometimes be misleading.” –BYU Student“I would have to search through every single one of these to find which one is a scholarly article and which one is just a newspaper article.” – Maryland Student
Broadening our goals“[T]he point of federated searching is to make searching as simple as possible” –CervoneIs it all about search?What happens before you search?What happens after you search?Re-search is more than just searching
Selecting the right resources“Nothing slows the user's scanning momentum more than encountering results that are irrelevant . . . many users view it as a digital equivalent of Tourette's Syndrome, where the system just spits out random items, unrelated to their search.”							– Jared Spool
Selecting the right resourcesWhy not search everything?Impractical technicallyImpractical presentationallyWhat you don’t search is equally as important as what you do searchWhy metasearch systems get this wrong(Overly-) focused on the search boxDefining is not the same as limiting
Once you start down the Quick Search path, forever will it dominate your destiny.
Desperately seeking search box“I just want a search box on the homepage.” 					– Your usersFirst Rule of Usability? Don't Listen to Users!What users say they do is sometimes different from what they actually do“The Google phenomenon”?
Desperately seeking search box“[T]here is something inherent in the site's design that causes users to choose the search engine or the links, not a hard-and-fast preference of the user” “[U]sers often gravitated to the search engine when the links on the page didn't satisfy them in some way.”							 – Jared Spool
Isn’t it ironic?The search box dominates the opening screens, then disappears!
Changing queries“Nearly all students repeated their searches, changing terms or subject categories, so the interface needs to make this easy.”– Maryland “Each new piece of information [users] encounter gives them new ideas and directions to follow and, consequently, a new conception of the query …  [T]he query itself (as well as the search terms used) is continually shifting, in part or whole.” –Bates

Avoid pogosticking“66% of purchases on [e-commerce] sites happened without any pogosticking . . . the more [users] pogosticked, the less likely the session would result in a purchase.”“The best search results pages will prevent pogosticking by providing the relevant content before the user chooses a specific result.” 							– Jared Spool
