Home Library Classification System
Catalog numbers tell where items are located in a library, and where they should be returned, as well as the subject or genre of each item. In this home library system, the catalog numbers are built from some or all of the following:
- Room Designations
- Form Designations
- Fiction Genres
- Music Classes
- Video Classes
- Subject Classes
In addition, shelving rules are used to augment the home library system when placing various items in their respective library files.
Room Designations (feel free to add or delete designations)
Rooms Designators
| Children’s Play Room |
C |
| Dining Room |
D |
| Hallway |
H |
| Kitchen |
K |
| Living Room |
L |
| Main library Room |
M |
Number your bookcases from left to right in each room, and letter the shelves from top to bottom in each bookcase. Some storage cases (such as those for audio, video, or periodicals) will not be numbered unless you have several storage cases for these formats.
Form Designations (feel free to add or delete designations)
Some items are filed according to their form (e.g., music recordings, video disks, etc.), and others are filed according to their usage (e.g., reference works, kits, and special collections). Designators are given for each form that needs special filing consideration.

Subject Classes (non-fiction)
A simplified version of Dewey works for non-fiction items in most home libraries. Use the broadest classification number that identifies the subject of each book grouping. Creating an entirely new system requires detailed study, and more time than most people want to spend. I will post another article on how to use Dewey, and locate the Dewey Numbers, for your collectionion.
The System in Action
The following examples show how to build catalog symbols with this system. Instead of labeling books and other items, you can simply enter these symbols in your library catalog. The following examples make the system easy to understand.
Example 1: For a spy novel located in the hall, found in bookcase 3, on shelf b, the book symbol is F.H3b.07
Example 2: For collected works of Mark Twain, located in the dinning room in bookcase 1 on shelf a, the symbol is F.D1a.04
Example 3: For an algebra book in the main library, found in bookcase 3, on the book symbol is N.L3d.512
Example 4. For the movie, “The Eiger Sanction” in cabinet 1 (Video) on shelf b, the symbol is V.1b.24
Example 5. For Beethoven’s 5th Symphony, found in cabinet 2 (audio) on shelf a, the symbol is A.2a.05
Example 6. For the Encyclopedia Britannica, in the main library, bookcase 5, shelf e, the symbol is REF.5a.031
Explanation of Examples
In Examples 1 and 2, the books are works of fiction. Thus, the first symbol is ‘F’ for fiction. The next symbol represents the room where the book is stored, ‘H’ for hall, and ‘D’ for dinning room, respectfully, and the last symbol (a number) represents the genre of each book.
Example 3 is a non-fiction work, indicated by ‘N’. The ‘L’ means that it is in the main library, and ‘3d’ tells you it is located in bookcase 3 on the 4th shelf from the top. Because it is non-fiction, the Dewey subclass for Algebra (512) is used.
Example 4 is a movie (video) recording, represented by ‘V’, and 1b tells you it is in cabinet 1 on shelf b. Finally, the number ‘24’ tells you it is a spy movie.
Example 5 is an audio recording represented by the letter ‘A’. It is in cabinet 2 on shelf a, and the final symbol, ‘05’, tells you it is a piece of classical music.
Example 6 is a reference work, indicated by ‘REF’. This is followed by the bookcase and shelf symbols ‘5a’, and then by the Dewey Class for general reference works in English (031).
Shelving Rules
Once books are sorted in order by the classification symbols in a computer, they are still somewhat jumbled. For fiction, the items are sorted by genre, but not by author and title. Non‑fiction items are sorted by subject class, but not by author and title. These shelving rules take care of detailed sorting.
- For fiction, inspect the items in a genre, then place the items in order alphabetically by the Authors’ last names, and then alphabetically by title within each Author’s name.
- For non-fiction, inspect the shelf for the appropriate subject class, and once again sort by authors’ last names, then by title.
- For non-fiction collected works (same author, multiple works), place them at the end of subject class—alphabetically by the authors’ names.
- If there are identical last names of Authors within the file, place the items according to the Author’s last name, then by the Author’s first name, then by title.
- For items with more than one author, sort by the name of the first author mentioned.
- Use uniform names and titles when shelving items in the library (i.e., Mark Twain instead of Samuel Clemmons, and “Hamlet” instead of “The Tragical Histories of Hamlet, Prince of Denmark”). Uniform names and titles help people find the items.
- For non-fiction anthologies—works by several authors about a single subject—shelve these works following collected works in the subject area.
- For fiction anthologies (e.g., a collection of science fiction stories by different authors), place the items at the end of all other works in the genre.
- For fiction, collected works in a single genre are placed after all other works by that author in the genre. For the collected works of authors whose collections span several genres, place the items after all other works of fiction.
If you use library cataloging software, and want it to sort by authors within the subjects or genres, you can add the first three letters of the authors last names after the classification symbols. With most such software, this extra work is unnecessary because multi-level sorting is a built-in feature. Some library software will print library cards, automatically adding the first three letters of authors’ last names. Check your software see if these features are included.
Notes:
- Major classification systems (Dewey, LC, etc.) arrange book on the shelves relative to one another. When you move books from one shelf to another to make room for new acquisitions, you do not need to correct the catalog entries.
- When books are moved from one shelf to another in the home library system described here, you must change the catalog entries to reflect the new shelves where the items are placed.
- There are solutions for this problem.
- Fill the bookshelves only about half full. This allows plenty of space for new acquisitions without moving items from shelf to shelf.
- List the beginning position (bookcase and shelf) for every book in a genre or subject area—no matter how many shelves the subject or genre spans. The catalog will tell you where the section begins, then you browse the shelves in that section for the specific item you want.
- Use a combination of the above solutions if you library is growing rapidly.
- If none of these solutions is suitable for your collection, you can use one of the major classification systems to provide for relative positioning of library items. You can retain the room designations, if you chose, for a library that spans several areas in your home.
- Adapt this system as needed; you can expand the classes or genres; you may add a designation for paperback books (PB), or any other specialized storage file. Keep in mind that the classification and cataloging system you use must fit your collection. Do not force your library to fit into an unsuitable classification or cataloging scheme.
- When deciding on your system, try to use standard subject or genre classes from a major classification system (Dewey, LC, or others). Their classes were created to minimize conflicts between classes, such as using ‘Domestic Pets’ and ‘Dogs’ in the same library. Because dogs are domestic pets, your collection will be split between these classes …and the shelves where they are stored.
