Pathfinder (library science)


A pathfinder is a bibliography created to help begin research in a particular topic or subject area.. Pathfinders produced by the Library of Congress are known as "tracer bullets". What is special about a pathfinder is that it only refers to the information in a specific location, i.e. the shelves of a local library.
According to the Online Dictionary for Library and Information Science, a pathfinder is "designed to lead the user through the process of researching a specific topic, or any topic in a given field or discipline, usually in a systematic, step-by-step way, making use of the best finding tools the library has to offer. Pathfinders may be printed or available online."
The goal of a pathfinder is to gather all of the most useful, relevant, reliable and authoritative resources on a variety of academic, work-related or general-interest topics. Originally provided in print format in the 20th century in large academic libraries, pathfinders have evolved with the emergence of the World Wide Web and may now act as portals to information about resources in a variety of formats, including books, encyclopedias, bibliographic databases, almanacs, documentaries, websites, search engines and journals.
Often used as curriculum tools for bibliographic instruction, the guides help library users find materials or help those unfamiliar with a discipline understand the key sources."

Purpose

Pathfinders are intended to be a launch point for research on a particular topic, via the collection of select materials available in a particular institution on that topic. However they are not generally an exhaustive collection of all of the materials on a given topic- they are designed for beginners in research to find the fundamental information they need to get started. Pathfinders also help to teach essential information and technology skills, and promote books and reading. They are broader in scope than subject headings, and have been chosen from university course descriptions, thesis titles, and from term paper titles. For public libraries, it has been suggested to use surveys, past experience and hot topics from local media to find topics for pathfinders. It has been argued to expand the purpose of a research guide from being a list of resources to also incorporating instruction on information literacy.

Format

MIT pathfinders in the 1970s had the following format:
Although the format varied, it emphasised subjects that were broad in scope and providing many different types of sources to the reader. In contrast, some academic libraries created specific pathfinders that functioned as a partial bibliography. In 1995, Jim Kapoun argued that key features of good pathfinders were "compactness and basic informational resources".

History

Booklists have been produced by libraries since at least the 1950s, but the term pathfinder was coined in 1972 by Marie Canfield. From approximately 1973-1975, the Model Library Program sold pathfinders among libraries, but there was not enough interest to continue selling pathfinders, as most libraries preferred to create their own.
From the mid-1990s, as the Internet became more popular, libraries began including web resources in their pathfinders and putting the pathfinders on their websites. Webliographies became popular, lists of web links that were curated by librarians on a topic. These differed from pathfinders because they did not focus on the library's collection. As library services became increasingly accessible online, options for creating online pathfinders expanded, including webpages, , and open-source content management systems.

Usage

Library clients can use pathfinders at their own pace, and may find them "more approachable" than a reference desk. Electronic pathfinders on a library website can be used 24 hours a day.
In higher education, embedding library subject guides into a learning management system has been shown to increase use of library resources among students. A 2011 study found that students often do not use library guides simply by not knowing they exist, or preferring to use a search engine or a trusted bibliographic database instead. This study found that students would use the subject guides if they didn't know where to begin, or if they were navigating a new discipline or if their lecturer told them to. While the stated audience for pathfinders are library clients, Jackson and Pellack reported that reference librarians regarded them as a useful tool for training and for librarians at the front desk. It has been proposed that creating and maintaining library guides may be considered a professional development activity for librarians.

Critique

It has been argued that pathfinders do not take a user-centred approach. Inconsistent formatting and overly-complex language have also been pointed to as being key points to watch out for. Some students become frustrated with dead links on subject guides, or the omission of resources that they consider essential. Maintaining and updating pathfinders is considered problematic. The use of Web 2.0 tools such as wikis and blogs are considered to be helpful in enabling smaller libraries to quickly update their pathfinders. It has also been said that librarians take a compilatory rather than a research attitude to creating a pathfinder. Little study has been done on how well a pathfinder covers its subject matter. A study found that pathfinders did not show the multi-disciplinary nature of literary studies well. Jackson and Pellack examined similar subject guides at different institutions to find out about duplication of effort in pathfinders. They found that there was little overlap between subject guides at different institutions, and that some websites used were of questionable quality. Furthermore, they found that libraries did not typically delete outdated pathfinders, because "something was better than nothing". When pathfinders at the course level are created, it may cause confusion to the students if the teacher also creates their own resources list, or faculty may regard the librarian as overstepping their role.
