Enβor Coordinator, Electronic Information Services Indiana State University, Terre Haute The fall meeting o f the Indiana Online Users Group focuses on expanding access to information. T he concept of the SuperCatalog is one that has recently received much attention— the focus of programs at ALA midwinter nual conferences in 1990. The recent implementa­ tion of the SuperCatalog concept at Indiana State University (ISU) in Terre Haute, Indiana, was the centerpiece of the November 9,1990, fall program of the Indiana Online Users Group. “Expanding Access to Information” was the theme. Fifty-three of the approximately 100 members of the state or­ ganization heard presentations which included a discussion and demonstration of LUIS II, ISU’s SuperCatalog. A SuperCatalog is a computerized library cata­ log that goes beyond providing access to a local library’s holdings. It may include access to (non- OPAC) locally produced databases, commercially produced databases loaded locally, information gateways to distant databases, and interlibrary link­ ages that allow transactions between different insti­ tutions. ISU brought up the NOTIS system in 1985. Since that time numerous enhancements have made it easier for users to access information. Among these are the implementation of keyword/ Boolean searching, loading of government docu­ ment tapes, and online access to serials holdings. ISU ’s movement toward the SuperCatalog model a began last August with the local loading of ERIC and a selection of H.W. Wilson databases. nd an­ Pre-im p lem en tation decisions Once the decision was made to load databases locally, the first question was: which software to use? The two realistic contenders in late 1989 were BRS Search Software and NOTIS Multiple Data­ base Access System (MDAS) software. The BRS software was well established and used for access­ ing multiple databases by several academic librar­ ies, including Clemson University, a NOTIS site. The BRS software allowed sophisticated search formulations and supported desirable print func­ tions; it also had been used to create local databases and worked with a wide variety of commercial databases. In comparison, NOTIS MDAS software was relatively new, it supported only a small range of databases, and did not initially support creation of local databases. It used the author, title, subject, and simple keyword/Boolean search capabilities of the NOTIS OPAC, which allow only one search statement and screen dumps for printing. NOTIS MDAS software had a number of advan­ tages for ISU, however. The overriding ones proved to be the retention of the same interface used to search the OPAC and ease of switching February 1991 / 95 from one database to another, including transfer­ ring a search from one database to another without rekeying the search statement. NOTIS was prom­ ising the capability o f linking article citations to OPAC serial holdings, a capability that would be more difficult to engineer with software from two different companies. Having both the OPAC and local database software from the same producer was bound to produce desirable working compati­ bility in the future. NOTIS was also willing to work with ISU toward developing a loader program for ERIC , one of the databases ISU wanted to load. After deciding on NOTIS software, we turned our attention to the question: What databases do we offer? This decision was based on three factors: user need, affordability, and availability through NOTIS. E R IC on SilverPlatter had proven popular with students during the preceding two years; queuing problems had resulted in two subscrip­ tions to the CD-ROM database. E R IC also met the affordability test and, as noted earlier, NOTIS was willing to develop the necessary loader program. A combination o f Wilson indexes (Social Science Index, Business Periodicals Index, Humanities Index, and General Science Index) was selected for loading as a single database. These particular in­ dexes were chosen because it was felt that they represented a broad range of subjects that would serve both graduate students and undergraduates. The E RIC and Wilson databases fit well with fiscal resources and mainframe computing space avail­ able at the time. N am ing th e new system ISU ’s OPAC had always been known as LUIS (Library User Information System). E R IC was an established database name and met the four-char- acter limit imposed by MDAS for database labels. Naming the Wilson indexes posed more of a prob­ lem, since we were combining four distinct indexes into one electronic database. Finally, W ILI was chosen as the name for the database containing the Wilson indexes. After the databases that would be available through the libraries’ new system were named, it became obvious that a new name was needed for the overall system. Library users already associated the name “LU IS” with the libraries’ “computer,” even though LUIS was technically the name of ISU ’s online catalog of local holdings. After much discussion, it was decided to rename the overall system LUIS II. This new name preserved users’ association o f “LU IS” with the libraries’ computer system. Using the numeral II implied a “new and improved” LUIS and offered flexibility for upgrad­ ing the name to reflect future enhancements. LUIS II would offer users a choice of three databases: LUIS, W ILI, and ERIC. O rg an izatio nal im p act Implementation o f LUIS II has had a variety of organizational impacts. Even before the new sys­ tem was implemented, staff training began, and will be ongoing due to a continuous rate of system changes and improvements. The Department of Library Instruction & Orientation (LI&O) pro­ vides general orientations for library staff on major system changes. Detailed training is done by NOTIS and individual departments. LI&O also promotes the new service to users, another ongoing concern. LUIS II was publicly introduced with a major promotional campaign which included a new symbol to convey the idea of LUIS II— a strongman holding three spheres, each with individual database names. A special issue of the library newsletter for ISU faculty, staff, and administrators featured LUIS II. LUIS II contin­ ues to be covered in all library instruction sessions offered by LI&O. Dial access to LUIS II has been a major concern. Access to E R IC is not as much of an issue, since it is a government-sponsored, non-copyrighted data­ base, but access to W ILI must be controlled. Data­ base producers understandably do not want cam­ pus databases to compete with their own online products. The library has always prided itself, however, on free public access to LUIS through dial-in. Reconciling these two concerns in a way that is not cumbersome to the user has now been done through a dial-access, front-end menu pur­ chased from another N OTIS institution and adapted. ISU Libraries reworded the two screens seen by the user, and they clearly make only LUIS available to non-ISU users, while allowing ISU users to enter their ID numbers and gain access to all three database options. The impact on interlibraiy loan requests is not yet fully known. An increase is definitely expected, since the library does not own all of the materials in W IL I or ERIC . Although users now have access to article citations in the library’s computer system, this still does not help the procrastinating student to obtain actual materials. Another major impact has been on computing equipment. These databases occupy a great deal of mainframe space— in the case of ERIC , more than was expected. This affects processing time for all searches, and some complicated E R IC searches simply will not yet run. This has implications for future investment of funds in systems equipment. Im p a c t on lib ra ry in stru ction The impact of LUIS II on library instruction efforts at ISU has been significant. Most obvious is the increase in instructional content for the usual 50-minute, one-shot lecture. Luckily, many faculty 9 6 / C &R L News who regularly request library instruction for their classes are allowing two class sessions for introduc­ ing LUIS II and other library concepts. The in­ struction librarians have begun to shift emphasis from purely mechanical, "how-to-search” proce­ dures to more cognitive concepts: database struc­ ture and fields; differences between databases in terms of content, purpose, coverage, and subject authority; and keyword/Boolean searching not specific to a particular database. The rate of system change brought on by NO­ T IS ’ continuing development of the MDAS soft­ ware poses another challenge. Instructional mate­ rials often need revision to reflect some improve­ ment in the system’s capabilities. Also, the rate of change makes it difficult for the instruction librari­ ans to stay abreast of all developments and keep end users and library staff aware of the changes. Perhaps the rate of change will lessen in the future as the SuperCatalog moves beyond its early stages o f development. In the meantime, the instruction librarians are learning to accept the rate of change as a challenge rather than an annoyance. Finally, changes specific to end-user searching (even though they are improvements) seem to diminish the year-to-year continuity of instruction efforts. What a student learns this year about searching in LUIS II may not apply after subse­ quent software releases are installed. Perhaps the time is near for a required course in information management for all students, or at the very least, more rigorous and pervasive course-integrated instruction. F u tu re developm ents The future of ISU’s SuperCatalog, LUIS II, is bright. A significant enhancement slated for the near future is what NOTIS is calling “hook-to- holdings.” Hook-to-holdings will allow users to determine very quickly the local availability of journal articles retrieved in an E RIC or W ILI search. A long-term project currently underway in Indiana is a statewide undertaking known as SU- LAN, State University Libraries Automation Net­ work. SULAN is a multi-phase cooperative effort which will ultimately allow Indiana’s library users to access the collections of participating institu­ tions’ libraries and initiate their own interlibrary loan requests. Making the transition from the single database/ OPAC model to the SuperCatalog is not entirely painless; however, it has been said, “no pain, no gain.” The concept of the SuperCatalog represents a new generation of online public access systems. One would be hard pressed to argue that the concept and the reality are not inherently good.
