Preface
The Standards Working Group is an adhoc
committee of librarians across Canada interested in developing a standard for
literature searching in the health sciences.
The inaugural meeting, where ideas were discussed along with the need to
formulate a plan, occurred in June 2014. The term “standards” was used at the
time, however after four years of reading and research, the concept has evolved
into a Code of Practice.
A wealth of literature exists with regards
to searching to support systematic reviews; in fact, several medical and
related organizations provide guidance on how to participate in systematic
review searching. However, in
comparison, there is very little written about standards for literature
searching. Opinions varied about whether
it would be possible to create a standard, given that each request and search
is different and unique. When requesting
searches, clinicians apply what is stated in the literature, along with their
own knowledge, to develop guidelines that focus on the patient’s needs to
determine the best approach to be taken.
A Code of Practice for literature searching can be a tool librarians can
use for evidence-based practice in librarianship.
Our intent was to research and document what
was described in the literature as well as applying our own examples and
experience to the information uncovered.
Once we gathered the required information, our research process included
sorting and ordering search methods within the Deming Cycle which evolved into
the steps and stages that the team analyzed.
A Delphi study was used to validate the work in 2015. The Research Ethics Board (REB) application
in 2016 contained two phases to continue to elicit feedback and validate the
work: a jurisdictional review and an
environmental scan of elite searchers.
While consultation with elite searchers has been conducted and evaluated
by the team, the jurisdictional review has not yet been completed due to time constraints.
During the research process, it was apparent
that a standard lexicon did not exist.
While there are glossaries contained in specific searching textbooks,
articles, or institutional reports, there was not one readily available for the
profession. The Glossary developed
includes the source and a link where applicable. The more current definitions researched have
been used unless an earlier definition provided a better illustration. The
Glossary should thus be considered a living document, which will grow and
undergo updates as needed.
A Code of Practice for literature searching
for librarians aligns our professional organizations with those of our
clinicians. The Code provides assurance
for our clientele that the profession’s approach to supporting clinicians’ work
uses the same standard of care and best practice that they must apply in their
own practice. It emphasizes the value placed on the library services and
librarian-mediated searching within the health care system. The Code provides a
basis for quality indicators or improvement, which can be used in literature
search instruction within library schools.
It may lead to the development of other ‘best practices’ or standards
for librarianship.
Writing the Code is simply the first step in
providing some guiding documents for the profession. It is our hope that continued investment in
the Code is undertaken to better identify issues that may be missing or include
future practice as it evolves.
Acknowledgments
Each member of the Working Group is grateful
for the support from our parent institutions, past and present, for the
opportunity to work on this project.
Lori Leger was an instrumental member in the early stages of work. Her contributions are evident in the steps
and stages. Lori was unable to continue
with the project. Special recognition is
needed to Amy Weisgarber from Regina Qu’Appelle Health Region (now the
Saskatchewan Health Authority) who used her talents to graphically represent stages
of our project in the posters created.
We would also like to thank the Dalhousie SIM search class, the Regina
Qu’Appelle Research Ethics Board, and all of the researchers and librarians who
took the time to provide us with feedback and new insights.

Proposed Code of Practice for Mediated Searching
This Code of
Practice is a first step at bringing together and sorting the mediated search
literature by:
·
type of search, labelled “search level” in this Code,
and by
·
search method, labelled “search step” in this Code.
1.1
Introduction to the Code
This Code identifies and defines each unique search method,
labelled generally as a search step,
groups these in general order within seven search
stages, then considers whether the step is required in each of five search levels.
The colours on each step contain meaning:
the step is not necessary
|
The step may be considered
|
The step should be considered
|
The step must be considered
|
The step is mandatory
|
1.1.1 Search Steps
The code identifies
eighty-six unique search steps.
Subsequent work may
include determining the degree to which each step is required for each search
level, i.e. “must”, “should” or
“may”, and classifying steps by
·
Type of method, whether search
strategies, search tactics, search operations or search moves;
·
Purpose of method, whether taken to
support individual search requests or to support aspects of the search service
more generally including such areas as inter-searcher communication, service
handover, information referral, client awareness development, resource
allocation and use, database selection, performance monitoring and service
evaluation.
1.1.2 Search

The code identifies five search types characterized by
increasing rigour and attention to detail.
