Cataloguing practice varies in most libraries, but the reasons for the various modifications in use do not enter into consideration here, the purpose being to show what are generally accepted as the best style and method. If care is taken during the present lesson to adopt a correct form of entry this will become more familiar to the student while covering the practice outlined in succeeding lessons, and the exactness and careful attention to detail which are so essential will thus be automatically acquired. Note the exact order in which the information should be given (see example on page _114_). Follow this in all practice, giving fullest information required by the particular form of entry being made out. The clearness and uniformity of entries are largely affected by punctuation and the extent to which items of the collation are abbreviated. The latter is too often overdone. Note the various abbreviations used and the considerations as to whether the gain of space is commensurate with the loss of clearness to the reader. Obtain a complete understanding of the respective uses of Arabic and Roman numerals, and the methods of giving the sizes of books. READING LIST.

To what extent would you carry abbreviation? _3._ Show the exact order in which you would give the information for a full author entry. _4._ In what ways are the sizes of books shown? Which method do you prefer, and why? _Lesson 3._ MAIN ENTRY. AUTHOR ENTRY. ANALYTICAL ENTRIES. Rules governing Main and Author entries take up the major portion of most codes of rules, but as they are better studied as a complete series they are all included in this lesson. It will be found that the various codes disagree in the form of entry for certain names, etc. Study the reasons for each variation, and after making comparison, attempt an independent decision as to the best form. Many of the rules are quite simple and easily remembered, but in those cases where the procedure does not appear to be straightforward the student is advised to trace a book which meets the description of the rule under consideration. In most instances the actual handling and examination of an example will assist one to grasp much more readily the instructions and the reason for the ruling.
