1. 1. How to find books using Dewey Decimal shelfmarkFind the book on the shelves! How to find books using Dewey Decimal shelfmark
2. 2. Introduction • When you look for books on the Library Catalogue you will be given a shelfmark, indicating where the books are held in the Library collection. • You will notice that some books have number shelfmarks and others have alphabetical ones. • We have two subject sequences in use in Birkbeck Library. • The majority of the stock is arranged in number order known as Dewey Decimal: Example 1 320 = politics 320.941 = British politics 320.973 = American politics • Some books have been classified by a scheme that uses letters known as Bliss : Example 2 YB = English Literature YD = English Literature in the 15th & 16th century YF = Shakespeare • This Learning Object focuses on the number sequence also known as Dewey Decimal Classification and will provide a quick overview of this and how to find the books on the shelf.
3. 3. What is Dewey Decimal • Dewey Decimal system is a hierarchical classification system used by libraries for organising items, from the broadest to the most specific topics. It was created by Melville Dewey in 1876. • The system is made up of 10 main classes or categories, each divided into 10 secondary classes or subcategories, etc. • In Dewey, basic classes are organized by fields of study. At the broadest level, Dewey is divided into ten main classes: 000 - Computer Science, Information and general works 100 - Philosophy and Psychology 200 - Religion 300 - Social Science 400 - Languages 500 - Science 600 - Technology applied science 700 - Arts and recreation 800 - Literature (in-house rule applies to specific country literature) 900 - History and Geography
4. 4. How is it organised • When you move among the shelves looking for the shelfmark that you found on the catalogue you will see that the books are arranged in numerical order and then alphabetically by the 3 letters at the end of the shelfmark. • The letters that come after the numbers are also important, particularly when there are many books which have the same number. The three letters denotes the first three letters of the first named author's surname or if the book has been edited, the first three letters of the title of the book (excluding definite and indefinite articles). • So always note down the full shelfmark given on the catalogue! • For the purpose of this Learning Object when looking for books on the shelf read the shelfmark by looking at the first three digits and noting whether the digits are 100s, tens, or unit. • The following screen shows the shelf pattern in the Library: across from left to right and from the top to bottom.
5. 5. The shelf pattern is across (from left to right) and from top to bottom
6. 6. Basic Example • When looking for books on the shelf read the shelfmark by looking at the first three digits and noting whether it is 100s, tens, or a unit. Example One: 701 ACT and 700 BAC • Having focused on the first three digits and put these in order (smaller to bigger number order) then look at the three letters and put that in alphabetical order. • Thus the order on the shelf would be: 700 BAC followed by 701 ACT {700 > 701} 701 ACT 700 BAC 700 BAC 701 ACT 700, no tens, 1 unit, ACT 700, no tens, no units, BAC
7. 7. Your shelfmark – bigger or smaller • The shelfmarks are arranged on the shelves from smaller numbers (broad and general) to bigger numbers (more specific) within the 10 main classes. Here is a collection of shelfmarks from the main classes mixed together. • Look at the first 3 digits of each shelfmark (arrange them smaller to bigger). Then having done that, look at the next 3 digits of each shelfmark and (arrange them smaller to bigger) keeping them within the main classes (if letters – arrange alphabetically) and repeat with the next 3 digits and so on if necessary. • Can you put them into the correct order – you have 20 seconds? 330. 216 AUB 287 MCC 428. 202 407 HIC 001. 196 BAK/ W 428. 003 FOW 428 DEW 428 BAK 150 GRO 150. 198 2 FRE 1 8 9765432 9
8. 8. Your shelfmark – how did you do? The Correct order is: 330. 216 AUB 287 MCC 428. 202 407 HIC 001. 196 BAK/ W 428. 003 FOW 428 DEW 428 BAK 150 GRO 150. 198 2 FRE 18 9 7 6 54 32 330. 216 AUB 287 MCC 428. 202 407 HIC 001. 196 BAK/ W 428. 003 FOW 428 DEW 428 BAK 150 GRO 150. 198 2 FRE 1 2 3 4 5 6 7 8 9
9. 9. Example 2 701. 015 BOA 700. 001 TAY 700. 005 PAC A B C First 3 digits Second 3 digits Alphabetical order Resulting order: Having put the first 3 digits in order the sequence would be: B, C, A or C, B, A Then within that having put the second 3 digits in order the sequence would be: B, C, A Following the alphabetical order of 3 letters the sequence is: B, C, A First 3 digits Second 3 digits Alphabetical order
10. 10. Example 3 709. 569 941 ACT 709. 568 941 KWZ 711. 570 941 ART A B C First 3 digits Second 3 digits Alphabetical order Resulting order: Having put the first 3 digits in order the sequence would be: A, B, C or B, A, C Then within that having put the second 3 digits in order the sequence would be: B, A, C Then within that having put the third 3 digits in order the sequence would be: B, A, C Following the alphabetical order of 3 letters the sequence is: B, A, C First 3 digits Second 3 digits Alphabetical order Third 3 digits Third 3 digits
11. 11. Learning outcome You should now know or understand the following:- • Who created the Dewey Decimal classification system. • The shelve pattern and how books are arranged on the shelves. • How Dewey Decimal works and how to find the shelfmark given on the Catalogue on the shelves.
