A library portal is an interface to access library resources and services through a single access and management point for users, combining the circulation and catalog functions of an integrated library system with additional tools and facilities.
Definition
A library portal is defined as "a combination of software components that unify the user experience of discovering and accessing information" in contrast to a "single technology" to provide "services that support discovery, access and effective use of information."
Major elements
In addition to the basic functions of access to the library catalog, and a user's subscription records, significant elements of a library portal normally include:
"Metasearching tools, browsable interfaces, and online reference help," which aid in the discovery process, for example Knimbus, Mendeley, J-Gate, EBSCO Discovery services;
More recently, the focus has been on the discovery goal, which has led to even more difficulties in defining a library portal. The terms "discovery tool," "discovery services," "next-generation discovery tool," "next-generation OPAC" are used interchangeably.
Current market
The focus on discovery tools has led to increased competitors in the discovery services market; the competitors that existed in the library portal market have also shifted their focus to this particular function. A list of competitors in the current library portal market who have recently been awarded contracts by various libraries for their entire portal include :
Axiell Calm: contract with Denmark’s Roskilde Libraries for archive management
BIBIS Library Portal: contract with ROC Mondriaan in The Hague as well as the library of the central bank of the Netherlands, the library of Provincie Zuid-Holland in South-Holland, and at Dutch law firm Ploum Lodder Princen.
ExLibris Primo: contract with Hesburgh Libraries of Notre Dame. Library Technology refers to this “discovery and delivery solution” as a “library portal”.
By contrast, the following list highlights contracts signed by libraries for specific discovery service tools, mostly at more recent dates
EOS.Web OPAC Discovery, EOS International: while it is unclear which of EOS services were purchased by their clients, the benefits to the EOS.Web OPAC Discovery grew significantly recently when EOS International signed an ILL agreement with the New York Law Institute, which will allow EOS clients to easily request NYLI union catalog items from their EOS.Web OPAC”. EOS International’s press releases do not specify which service was purchased but only mention the names of new clients.
When building a portal for a library, one of the challenges discussed by Morgan is communication: the building of a portal requires consensus with regards to what should be included. Another challenge is ensuring a user-centered design for the portal. This involves conducting surveys, focus group interviews, and usability studies – all of which can be seen as time-consuming. Additionally, compatibility with the hosting institution is critical. Finally, the question of whether a library should go with open source software or commercial products is always a point of contention.
Standards
There are no accepted standards for library portals. The only standards in the literature are the more general search and retrieval standards, including Z39.50 and ZING, the Open Archives Initiative Protocol for Metadata Harvesting, and OpenURL. As a result of the lack of standards, and since customization is required in a library portal, individual institutions decide what they expect their portal to look like, and what services it will provide. For example, Harvard University is currently conducting a library portal project, which will begin implementation during the summer of 2012. They have identified their own list of criteria, which naturally differs substantially from the needs of other institutions. The various general areas that the committee has looked at include: content, user experience, features and capabilities, infrastructure and security, and search and discovery. It is uncertain which areas will be selected as part of the Phase I implementation of the portal.
Relationship between OPACs and library portals
The online public access catalog is a basic module, part of the library’s integrated library system. Earlier, the OPAC has been limited to searching physical texts, and sometimes digital copies but has only limited special features. Caplan argues that they are in process of replacement by newer "discovery tools" allowing more customization. Yang and Hofmann suggest that vendors see money in building either separate discovery tools or Next-Generation OPACs to be purchased as an add-on feature. A problem with vocabulary arises here. Yang and Wagner refer to discovery tools by many names, including "stand-alone OPAC, discovery layer, and next-generation catalog " This contrasts Bair, Boston, and Garrison, who differentiate between next-generation catalogues and web-scale discovery services. Despite any confusion, it is clear that the OPAC as it currently stands is outdated, and will be replaced by more modern, user-friendly tools. The next-generation OPAC as described by Yang and Hofmann will ideally have the following 12 features :
