A Bibliography Cross-Reference System
April 1984
Harding University
Searcy, Arkansas
CHAPTER 1
Getting Started with Bibliog
This first chapter is designed to acquaint the user with Bibliog and the new
terms used in Bibliog. It also gives an overview of Bibliog's options and
tells the user the basics necessary to get started using Bibliog. Instructions
about wise usage, error messages and other very important items concerning the
serious user are contained in later chapters. It is advised that the user read
completely through this documentation before attempting to set up his own
bibliography file system; however, one who is going to use an already existing
system should be able to begin work after carefully reading this first chapter.
1.1 New Terms Used in Bibliog
ADD ENTRIES The main option that will add another entry to the user's
bibliography file.
ADD SUBJECTS The Manage suboption which adds subjects to the main subject
list.
BIBLIOGRAPHY The general term for the file that is created by Bibliog of
FILE filetype .BIB containing the entries in the user's bibliography
file.
CARRIAGE RETURN This term is abbreviated by <CR>. It is the key on the
keyboard which is labeled RETURN or NEW LINE. Usually this
symbol is associated with default answers to a question.
CHANGE SUBJECTS The main option that will change the subjects under which an
entry is classified.
DEFAULT The term referring to any automatic answers to a question that
are invoked when the user types <CR> in reply to that question.
DELETE ENTRIES The main option that takes entries out of the user's
bibliography file.
DELETE SUBJECTS The Manage suboption that takes subjects out of the main
subject list.
1.1 New Terms Used in Bibliog (cont.) Page 1-2
ENTRY An entry is the reference of one book or article that is
entered by the user. Its format is as follows:
Title:
Reference: Year:
Author(s):
Subject(s):
HELP The keyword that will print a message to the user at any point
in the program helping him/her to correctly answer the current
question.
INPUT A term describing the typing of information into the computer.
LIST ENTRIES The main option which will list entries specified by the user
either to the terminal or to an independent file.
LIST SUBJECTS The Manage suboption which will list the subjects in the main
subject list either to the terminal or to an independent file.
MANAGE SUBJECTS The main option which allows the user to define his/her main
subject list before typing in any entries.
OPTION A choice of several possible answers to a question in Bibliog.
OUTPUT FILE An independent file in which the data specified by the user is
stored.
PROMPT A message printed by Bibliog that asks the user for a response.
REFERENCE FILE A file created by the user which prints out when help is typed
in reply to the prompt 'Reference?' allowing the user to define
his/her own referencing standards.
SUBJECT FILE The general term referring to the file created by Bibliog of
filetype .SUB that contains the main subject list for the
bibliography file.
SUBOPTION A choice of several possible answers to a question while
using a main option of Bibliog.
TITLE SEARCH The main option in Bibliog that references an entry by
searching for a matching word or phrase in each entry's title.
1.2 The HELP Command Page 1-3
Bibliog's HELP command is a unique feature that is very useful, especially to
the inexperienced user. Essentially, the HELP feature can be summed up by
saying that the keyword HELP can be typed in answer to any question in Bibliog
and a message telling the user what kind of answer is expected will be printed.
The user will then be returned to the question that is to be answered. There
are very few instances in which the keyword HELP can be abbreviated so, to be
safe, it should be typed out each time until the user is certain that it can be
abbreviated at a particular question.
In some instances, an incorrect answer to a question will cause the same
message to be printed as the keyword HELP would cause. This is to help the
user correctly answer the question without giving him an error message.
Some questions print special messages when HELP is typed. At a request for a
subject, HELP will print a list of the available subjects in the main subject
list, thus enabling the user to classify his entries under existing subjects.
Typing HELP at a request for a reference can print a user defined message; to
learn more about this read the section in chapter 2 on setting up your own
standards.

1.3 Options Available in Bibliog (cont.) Page 1-4
Hopefully, the preceeding chart will help the user become acquainted with the
basic structure of the options available in Bibliog. The next few paragraphs
give a short overview of each option in the above chart.
Add Entries The Add Entries option allows the user to include new entries
into his bibliography file.
Delete Entries The Delete Entries option allows the user to remove unwanted or
incorrect entries from his bibliography file.
Change Subjects The Change Subjects option allows the user to reclassify
of Entries entries which have been incorrectly classified or classified
under an out-of-date set of subjects. Subjects can be added to
or deleted from the entries.
List Entries The List Entries option allows the user to print a list of
specified entries either to his terminal or to an independent
file that can be printed off on a hardcopy terminal. The
entries can be specified by Author, Subject, Reference or a
Title Search for a certain word or phrase contained in the
entries' title.
Manage Subjects The Manage Subjects option allows the user to create a list of
subjects that he wants entries in his bibliography file to be
classified under before actually entering any entries into his
bibliography file. For more information on managing subjects,
read the section in chapter 2 on setting up your own standards.
Exit Program The Exit Program option allows the user to stop using Bibliog
and return to the $ prompt of DCL.
1.4 Default Answers to Questions in Bibliog
All questions in Bibliog have some type of default answer. Defaults vary for
different questions so caution should be exercised when using them.
Any possible answer to a question that is printed inside these symbols <>
directly after the question is the default for that question. Other implied
defaults do exist but they do not concern the beginning user. To invoke a
default, simply type <CR> in response to the question.
Abbreviations of any length for keywords such as Add, Delete, and Exit can be
used. EXCEPTION: HELP, in almost all instances, cannot be abbreviated to
receive the help message. Take care in typing HELP so that errors can be
avoided.
Some particular defaults deserve attention here. The default to the
question 'Output File<Terminal>?' is that the desired information will be
printed on the terminal screen instead of in an independent file. Also, if an
entry is added without subjects or all of an entry's subjects are deleted, the
entry will be classified under NONE by default.
1.5 Exiting Options and Suboptions in Bibliog Page 1-5
How can a user move on to the next question or go back to the 'Option<Help>?'
prompt when he is finished using an option or suboption in Bibliog? Usually,
he can simply type <CR> in response to the current question and he will move to
the next question in that option or go back to the main prompt if he has
finished with the option. For example, if a user is adding new entries and
does not have the data needed for a question, he can type <CR> and skip that
question. Essentially the same thing happens if he has added to an entry all
the subjects or authors that he has for that entry. He types <CR> in response
to the prompt for the next subject or author and moves to the next question.
There are some options in Bibliog that do not default to the next question when
<CR> is typed. These options are discussed below.
The List Entries option does not exit when <CR> is typed in response to the
prompt for an author, subject, or phrase to use to list entries. It will
have a wildcard type effect and will print all the entries in the user's
bibliography file. If List is entered by mistake and no list is desired, then
the user should type a character or word that he knows will not be matched.
He will then be returned to the main prompt with the message 'No entries
matched.'
Suboptions in the Manage Subjects option are exited in the same way as other
options, but the Manage option itself must be exited by typing EXIT in
response to the prompt 'Manage Subjects Suboption<Help>?'.
Bibliog can be exited by typing EXIT in response to the prompt 'Option<Help>?'
when the user is finished running the program.
CHAPTER 2
Setting Up a New Bibliography File
This chapter is designed for the more serious user who wants to set up his own
bibliography file system. It contains hints about wise use of subjects, saving
disk space and other things to make use of Bibliog easier and more profitable.
2.1 Establish Good Standards for the New Bibliography File
The first and most essential step in setting up a new bibliography system is to
establish a good set of standards and follow them closely throughout the entire
bibliography system. The following steps are necessary to establish standards
that will make the user's bibliography file easier to use and much more
valuable to him.
2.1.1 Create a Main Subject List
This step is accomplished by using the Manage Subjects option of Bibliog. The
user should write down a comprehensive list of subjects under which he would
like all of his entries to be classified. Then the user should enter this list
as his main subject list. When any entries are added that do not fall under
these subjects a new subject can be added to the main subject list or the entry
can be reclassified. Similarly, a subject in the list not used as predicted
can be taken out of the list by using the Manage option later on in the Biblio-
graphy System's development. Hopefully, using this method will prevent
entering entries under more than one scheme of classification and prevent
misspelling of subjects for an entry. For example, if a subject was entered
under USA and another was entered under AMERICA, the two would not be
accessible at the same time and a loss of efficiency would result. More
information about what schemes of subject classifications are most efficient is
contained later in the chapter.
2.1.2 Set Up Standards for the Entry of Authors
The computer thinks that 'Doe, J' and 'Doe, J.' and 'Doe, John' are all
different authors, although they may very well be one and the same. This
illustrates the need for uniformity when entering authors into ones biblio-
graphy file. Special attention should be paid to the following areas in which
many people could encounter problems. Specify whether authors should have
their names spelled out or initialized and, if they are initialized, whether
to have one or two initials. Also, decide if they are to have periods after
the initials or not. Whatever standards are agreed upon, be sure that all who
enter data for the file know them and follow them very closely.
2.1.3 Set Up Standards for the Entry of References Page 2-2
References are similar to authors in that many people wish to enter them in
different ways, some by the Dewey system, others by a system of their own.
A method is provided to make sure that your files all use the same referencing
system. After a method is decided upon, create a file using EDT named the same
as the bibliography file with the file extension '.REF'. Put a message in this
file telling those who use your bibliography system what referencing standards
are desired. This file will print out exactly as you enter it when the user
types HELP in response to the prompt for the reference of a new entry.
2.1.4 Variations of the 'Year:' Usage
Although this classification is limited to four characters, any four charac-
ters, whether numbers or letters, may be used. The user will probably just
enter a year but may decide that another small piece of information about his
entries would be more important. Whether the user decides to use this option
or not, he should be sure that all who enter data into his bibliography know
his conventions for the 'Year:' specification.
2.2 Using Disk Space Wisely
Some schemes of classification are much more profitable than others because
they limit the amount of entries classified under each subject by the use of
more restrictive subjects. For example, if entries are classified under USA,
there may be too many entries that are classified under such a broad subject
for it to be useful. A better classification would be USA, EARLY or USA, AR
depending on what was most important to the user, time period (EARLY) or
location (AR). This would save disk space by making listings of entries more
restricted and by eliminating the need for having many subjects for the same
entry, i.e. the entry above could be under USA, AR instead of USA and ARKANSAS.
Any scheme of classification may be used but the user should make sure his
scheme is closely followed at all times when people are entering data for him.
Another way of conserving disk space is to use care in entering data so that
deletions are rare. To change incorrect entries of author, year, reference, or
title, one must delete the entry and re-enter it. Unfortunately, the way the
bibliography files are set up, space that is emptied by deleting entries cannot
be accessed for another entry, so it is wasted. Clearly, the fewer the
deletions, the more efficient the file will be.
CHAPTER 3
Sample Runs of Bibliog
This chapter contains actual dialogue from runs of the Bibliog program. It
is to be used as an example to the user of questions, proper answers,
messages, etc. that will be encountered when running Bibliog. Any lines that
begin with an exclamation point are comment lines. They are NOT part of the
actual dialogue.
