ABSTRACT
The purpose of
this study was to assess the back of the book indexes in Natural Science books
published in Nigeria. But the specific objectives of the study were to
determine: how indexes are provided in
the Natural Science texts sampled; the extent to which basic indexing elements
are provided; the depth of indexing; the filing and arrangement pattern of the
index entries and finally, if differences exist in the indexes of secondary
school texts and tertiary/general Science books. Four research questions guided
the study, and a structured checklist was adopted and used to obtain
information to answer the research questions. A descriptive design using document
examination was adopted for this research. The researcher used the accidental
sampling technique to sample books in the Natural Sciences. All the books
published in the Natural Sciences in Nigeria within the period 1990 –
2010 constituted the population of the study. Sixty books were sampled, 35of which had indexes, while 25 of them
had no index. The data collected were organized in tables and analyzed, using
simple percentages, frequencies and histogram. The findings revealed that: many
Nigerian published books in the Natural Sciences lack back-of-the-book indexes;
most index entries lack sub-headed entries and semantic relationship; cross-references
– ‘see’ and ‘see also’ were very few; the filing order and arrangement patterns
of the index entries were in line with international standards and no
outstanding differences were found in the indexes of secondary school texts and
tertiary /general Science books. In view of these findings, the study
recommends that book publication in Nigeria should be assessed and controlled.
Nigerian Information professionals should set up standard indexing outfits to
be manned by professional indexers who should handle book indexing in Nigeria;
public enlightenment programmes should be carried out by information scientists
from time to time to enlighten publishers and authors on the importance of indexing
in their work. Finally, further research in this area of study was suggested by
the researcher.
CHAPTER ONE
INTRODUCTION
Background of the Study
The concept of book is derived from
an early English word boc, which means tablet or written
sheets. A book consists of written or printed sheets of paper or some other
material fastened together along one edge so it can be opened at any point.
Most books have protective cover. According to Ellenbogen (2004) Books are
inexpensive and convenient way to store, transport, and find knowledge and
information. There are different forms of books, namely, story books, textbooks,
workbooks, comic books, novels, almanacs, dictionaries, encyclopedia, telephone
books, etc. But the Natural Science books and the general Science books or
general non-fiction fall under the category of books regarded as textbooks
TheNatural Science is a systematized body of knowledge based on
observation and experimentation. It deals with the phenomena of the universe
and its laws – physical and natural. This branch of study is especially
distinguished from the arts due to its empirical method of enquiry. The subject
disciplines studied under natural science include: Physics-(Phy),
Astronomy-(Astr), Chemistry-(Chem), Biology-(Biol), Geology-(Geol),
Paleontology-(Paleo), Zoology-(Zoo), Botany-(Bot) and Microbiology-(MCB); (
LCSH: Schedule, 1996).
With information explosion, (i.e. an
extensive increment in the field of knowledge and knowledge output in different
disciplines) especially in the Natural Sciences and their concomitant complex
concepts; compounded with the increasing reservoir of both books and non-books
(that is, on-line documents) that contain the information in demand, information
retrieval has become a daunting problem. In fact, not only is information retrieval
becoming more problematic by the day, but the retrieval systems are also
becoming complex too. Hence, the emphasis is the need for information retrieval
systems that will match the retrieval need of information documents by end
users.
Thus, Lancaster (1991) and Chowdhury
(2004) have identified a number of information retrieval subsystems namely: document
subsystem, indexing sub-system, user-interface and matching sub-system.
However, among these subsystems only the indexing sub-system can adequately
perform an effective retrieval operation. An indexing system, as observed by Lahtinen
(2000) is a set of prescribed procedures (manual/or machine) for organizing
contents of records of knowledge for purposes of retrieval and dissemination of
information. This is done by organizing an appropriate guide call index into a database.
Indexes are extracted words and
phrases joined together, and structurally designed to make searching through millions
of pages very fast. (Croft, 2004). The British Standards Institute (BSI 3700: 1988) describes an index as a
systematic guide to the text of any reading matter or to the contents of a collected documentary material comprising a
series of entries with headings arranged in an alphabetical order, or any other
chosen order and with references to show where each item indexed is located. The
extracted words and phrases which form the index entries, as pointed out by
Croft, are not just a list of words but serve as organized maps and guide through
the several pages of a text. Mulvany’s (1994) definition that seems to sum up the
others, stated that, an index is a structured sequence – resulting from a
thorough and complete analysis of the text—of synthesized access points to
all the information contained in the text. The structured arrangement of the index
enables users to locate information efficiently. Perhaps, this is why Walls (2009) has also likened it to a
complete body x-ray – an abbreviated, in-depth view of every important topic
and sub-topic, along with locators guiding the reader to the actual pages for
quick, deeper inspection of critical areas.
It is perhaps for this reason that Olason
(2000) also concluded that the primary purpose of an index is to support the
user in practical application of knowledge. It does this by providing the most
efficient access map to information – or data plus context – embedded in the
material. It is therefore pertinent to add here that an index is not only a
guide but a search tool and a mirror that gives at-a-glance view into the body
of a document.
Indexes are therefore very
important tool in information retrieval, for they help to ease off the stress
involved in research, by providing easy access to information resources. This
is particularly so for a good quality and effective index which searches for pertinent
data and ignores the irrelevant ones. In other words, a good index distinguishes
between substantial (significant) and insignificant (i.e. one-time mentioned)
information. At the same time, it can provide some terminologies not explicitly
present in the text (Lukon, 2004). Accordingly, fruitful literature search is
guided by the index. This is because it enables the reader to achieve direct
information retrieval with minimal or no strain at all. An effective index also
leads the user to all the pertinent information on a given topic in the work or
works indexed (Knight 1979). Furthermore,
indexes have been observed to contribute significantly to works of knowledge or
imagination (Afolabi, & Daudu, 1994). Indexes provide a gateway to the author’s ideas
and serve as a road-map to the contents of a book. In other words, an index, as
an information retrieval system, serves as a bridge between the world of
creators or generators of information (i.e. authors) and those of the users of
that information, i.e. the end users. Also, a good index can give the author a
new perspective on the effectiveness of his/her presentation (Osgood, 2008).
According to Pyne (2007), the quality of an index also affects marketability of
non-fiction books. In other words, high quality index promotes the
marketability of such books, while poor quality index or even absence of it has
a reverse effect.
In fact, poor quality index does not,
unfortunately, provide the easy and fast access they are expected to give.
Rather, they are either too scanty or too lengthy and clumsy and seem to
rewrite the book itself. A lengthy index could force the user to study the
index structure before proceeding to the main work. As Knight has argued, if an
index cannot lead its user to the information sought for, or omits and fails to
point out information not suited to the user’s needs, the index has failed its
purpose. This sort of situation often
is frustrating to the user of the index. Inadequate or poor quality index makes
retrieval of specific information very difficult. It also makes the work of
librarians who deal with users’ queries and constantly make use of indexes to
trace information in a text less effective (Lancaster 1991).
However, with the functions of indexes indicated above, arise their
relevance or necessity. Indeed, the usefulness of an index is too central to be
overlooked. This is why experts lay stress on this matter. For instance, Knight
(1979) suggests that any publication beyond the size of a pamphlet is
incomplete if a full index is not added to that publication. Also, Preschel (1981)
in Lancaster, 1991), in discussing the issue of indexable documents stressed
that,
All text information of a substantive nature
should be indexed. ‘Substantive’ is here defined as information that covers
8-10 text lines or that is unique or outstanding and will almost certainly not
occur elsewhere in the encyclopedia. P13.
Due to the importance of book
indexes, publishers, authors, critics and indexers are generally agreed that
certain classes of books must be indexed. These may include text books, in all
fields of knowledge, and at all levels of academic pursuits, (Afolabi &
Daudu, 1994).
Unfortunately,
in spite of these admonitions, guidelines, suggestions and agreement, serious
indexing lapses have been observed in many a text. Publishers and authors have
been known to neglect to add index to some of their books. When this happens,
most information in such books become difficult to access quickly and so is
easily forgotten. Such books are often held in low esteem by users. Suffice it
to add that, it is not only the absence of an index that may cause a text to be
held in low esteem but poor quality of the index could make the text unpopular
because it lacks a good and concise index. This is why Bella (1996) has
stressed the need for indexes to be as precise and direct to the point as
possible. In this regard, he argued that the system that meets the basic
criterion of satisfying the reader’s need is the Back-of-the-Book (BOB) index;
which has a simple structure and provides access to natural language terms.
(This is an index term that uses direct language of the document)
The Book Index, also known as the back-of-the-book index, (BOB refers to the content summary at the back of non- fiction books.The BOB is a type of printed index that offers ready access to items of information in a book. Entries may be the names of persons, corporate bodies, places or concepts to represent subjects, (Tulic, 2008), followed by page numbers on which information is to be found. Terms must reflect the contents of the book and vary from one book to another (Rowley, 1992). Though other indexes abound, the researcher is paying particular attention to back-of-the-book index, also call “BOB” because of its variations in style of indexing; and its usefulness in providing access points to important information in a book document, particularly its use in the provision of access points to information in natural science books, which often have complex concepts.
From the on-going, discourse, BOB index is a unique information retrieval system which may vary in design and style according to the indexer. But no matter the variations and styles employed, the critical thing is that the whole essence of indexing is observed. That is to provide access to bibliographic information; using basic indexing elements or variables, and making the index as simple and straight to the point as possible. Some of these indexing elements or variables for back-of-the-book indexes include: Scope Note, Heading (indexing word or phrase), Sub-headings, Control Devices- Locators and Cross references, Index Density, Arrangement/ Filing Order, Physical Appearance, etc. The use of any of the listed characteristics depends on the choice of the indexer and is acceptable as long as they conform to global standards and are approved by standard bodies such as American National Standard Institute (ANSI, 1984) and British Standards (BS: 37OO, 1988) that moderate indexing standards. The above listed basic indexing elements or criteria are also used to analyze and evaluate or assess the quality and effectiveness of an index in information retrieval.
