Early in 2005 staff at the Health Sciences Library System (HSLS) at the University of Pittsburgh introduced a federated search tool for their collection of over 2,500 eBooks.  HSLS serves the six schools of the health sciences at the University plus the fifteen hospitals that are part of the University of Pittsburgh Medical Center (UPMC) and located throughout western Pennsylvania.  HSLS staff determined that the eBooks would be useful during patient care, but believed that patrons would be hindered in trying to locate relevant information, both in trying to identify useful titles and in having to separately search each title or platform.

The “Google-like” search uses the Velocity search platform from Vivisimo as its search interface (also used by The National Library of Medicine and Womenshealth.gov).1  Although there were other products on the market, HSLS staff chose the Vivisimo product for three reasons: 1) Vivisimo was a local company, 2) company staff were willing to partner with HSLS in development of the search tool, and 3) the price was competitive with similar products on the market.  The intent was to provide better access to the eBook collection, especially for users seeking quick information for patient care or for users who worked in UPMC hospitals without on-site libraries.2  Early in the development of the eBook search, HSLS had recognized our users’ needs to “seek smaller and more specific content units.”3  Our work coincides with recognition by others in our specialized field of health sciences literature that a major barrier to eBook adoption was discovery.4  Our eBook search provides a quick way for researchers and clinicians to get detailed, specific information from our large collection of eBooks (currently over 1,000 in health and biomedical science).  The eBook search is not designed to search journal literature because HSLS users use databases such as PubMed and know when the information they need would more likely be found in eBooks.

The eBook Search

The eBook search accesses content on eight platforms from a variety of publishers and aggregators of health sciences titles.5  Restrictions on some publisher’s/aggregator’s platforms occasionally have made it difficult if not impossible to search the content of their eBooks.  With one aggregator we had to wait a year until their system was configured to be compatible with Velocity.  Currently we are unable to search one of the publishers because the search isn’t working after they made an upgrade to their platform.  In some instances where we do not have site licenses, but pay only for a limited number of seats, we have been gratified that most publishers/aggregators have allowed us to use an extra seat for searching that doesn’t count against our concurrent user seats.

The eBook search has been very successful.  HSLS staff track the usage of the eBook search using WebTrends software.  From March to October 2005 (after the search was developed), there was an average of 251 searches per month, and in 2010 there was an average of 2,693.6  Statistics gathered from McGraw Hill for the AccessMedicine package may also demonstrate the increased use of the eBook search (and of the eBooks in general).  In 2005 there were a total of 9,680 searches recorded on the Website; in 2010 that had increased to 60,238 searches for the year.

HSLS users have multiple ways to access eBooks licensed by the library.  They can do a search for the title from the Pitt Resources Quick Search box on the main page of the libraries’ Website (http://www.hsls.pitt.edu/), search for the title in the online catalog (http://pittcat.hsls.pitt.edu), browse eBooks by subject (http://www.hsls.pitt.edu/resources/books/ebooks), or use the eBook search (http://tinyurl.com/3bruveb).

Patrons enter search terms in the search box, much like they do in Google.  They can be common keywords (cancer, heart attack) or more clinical terms (neoplasm, myocardial infarction).  Results are displayed in a ranked order based on relevancy.  One excellent feature of Velocity is the clustering technology that narrows the results.  In the HSLS eBook search, patrons can select a narrowed topic (elevation myocardial infarction, acute myocardial infarction) or a specific resource.

Patrons have adopted this new tool with great ease and few need instruction from the librarians.  Although the library has done a limited amount of usability testing, few changes have been needed.

In a recent study, Folb examined eBook use at HSLS including patrons’ use of eBook search tools, including Google Books.  The eBook search tool was used by a large percentage of people (67%) and was rated as moderately to extremely useful by 74%.  Google Books was rated the same.  Patrons gave a somewhat lower rating to the library catalog (61%), rating it moderately to extremely useful.7

Other Federated Searching
Products at HSLS

The use of Vivisimo’s Velocity for federated searching at HSLS has led to development of other, more specialized products, focusing on content in specific health science areas such as clinical medicine and bioinformatics.  HSLS molecular biology librarians have a rich Website that provides access to a variety of resources for researchers at the University and UPMC (http://www.hsls.pitt.edu/molbio).  Velocity is used for searches of numerous discrete groups of materials, including the extensive collection of licensed protocols such as Cold Spring Harbor Protocols, Methods in Enzymology, and Current Protocols.  Researchers appreciate the opportunity to search in one place for needed protocols.

Within the last few years reference librarians have worked with the HSLS programmers to develop a clinical tool that uses the Velocity technology to search a pre-selected set of full-text “answer tools” and electronic textbooks.8  Initially named Clinical-e9 it has been redesigned and renamed Clinical Focus.  Clinical Focus allows a user to search for information about a disease, symptom, drug, procedure, or test from a single search box.  The goal in developing Clinical Focus was to embed it in the UPMC electronic medical record, or eRecord, to provide easy access to the library’s knowledge-based resources at the point of care.  Currently, Clinical Focus is available to clinicians via the inpatient and outpatient eRecord.

Future Plans

HSLS continues to have an excellent relationship with Vivisimo as we continue to find new uses for Velocity.  We have recommended its adoption to other libraries, and the Houston Academy of MedicineTexas Medical Center Library is currently a Vivisimo Velocity customer.  Because of our continued success with the product, we have no plans to investigate other products.

We will continue to monitor the use of the library’s eBook search as well as the other search tools this project created.  The library will also look at other innovative ways to use this technology to aid our users in quickly finding the information they need.
