. . . and type in your LC term in the box provided:
If you don't know what LC subject heading to use, see Finding a valid LC subject heading for tips on how to identify appropriate LC subject headings.
Finding a Valid LC Subject Heading
If you don't know what constitutes a valid LC subject heading, do a subject word search, and in a relevant record, scroll down to the field that says Subject:, highlighted in blue in the screen shot for a record from the "Buddhism" search below:
Subjects listed in this field, like "Buddhism" highlighted in the screen shot above, are legitimate LC subject headings; if you click on them, they will search for all other records in our catalog that have that specific LC subject heading assigned to them.
If you're in the library, you may also use the five-volume Library of Congress Subject Headings set, located in the library on the index table near the reference office, to identify valid LC subject headings. (Ask a reference librarian for assistance.)
Refining Your Search
Expanding Your Search
If you're having trouble finding relevant searches on your topic, try some of the following techniques to expand or broaden your search:
- Search the catalog using the LC Subject Headings search function instead of the subject word function. Doing so often gives you more numerous and more focused results. See Example 1 and Example 2 above. If you need help identifying legitimate LC subject headings, see Finding a valid LC subject heading.
- Use the word "or" between synonymous terms. Doing so will instruct the catalog to look either for one term or the other, but not necessarily for both, therefore resulting in a larger number of records to explore. For example, if you type "frogs or toads," you will find more records than if you typed in only one term or the other.
- Use truncation (the asterisk symbol: *) to stand in for different endings on the same root. For example, if you're searching for information on computers, you can type in the root "comput" followed by an asterisk--comput*--in order to retrieve records with the words "computer" or "computers" or "computing" or "computation," etc. The asterisk acts as a wildcard symbol in words with the same root, standing in for any and all letters that follow it. Using truncation means you don't have to do multiple searches to find all the variations on a given term.
- Take advantage of "related subjects" and "see also" references. When you do an LC subject headings search, sometimes one of the subject headings options is your term followed by "related subjects."
For example, if you do an LC subject heading search for "sports medicine," you'll get a list of LC subject headings that includes "Sports Medicine--6 related subjects," as indicated in the screen shot below:
If you click on this link, you'll then get a list of 6 "see also" references that suggest other LC subject headings related to that of "Sports Medicine." These include "Doping in Sports," "Sports Injuries," and "Sports Physical Therapy," among others, as illustrated in the screen shot below:
Clicking on these "see also" links produces a list of all the records with each particular LC heading assigned to it, as illustrated for "Doping in Sports" below:
Using the "related subjects" and "see also" LC headings increases the number of places you're looking for similar information, therefore broadening or expanding the original number of links to records that cover similar subjects to the original one of "Sports Medicine."
Narrowing Your Search
If you're overwhelmed by too many hits (25 is probably the maximum number to deal with comfortably at a time), experiment with some of the following ways to narrow your search. (Narrowing either reduces the number of results or re-sorts them into a more manageable order.):
- Add additional terms. Let's say you're looking for information on the etiquette of doing business internationally. If you do a subject word search for the phrase "business etiquette," your search would pull up 44 records with those terms in them (a good bit over our target of 25 or fewer records). To narrow that set down, add the term "international" by typing in the following subject word search: "business etiquette international". Doing so will result in 12 records on your topic. The more terms you're searching for simultaneously, the smaller your list of results.
- Search by LC subject headings instead of by subject word. If you're doing a subject word search, you often get more hits than are relevant, and by searching instead by LC subject headings, it focuses your search by reducing the number of records to only those that are relevant. See EXAMPLE 1 above to see how this works. See How to search by LC subject heading and Finding a valid LC subject heading for more detailed instructions.
- Sort results by date of publication. After you conduct a search (whether it's by subject word, LC subject headings, author, title, etc.), you can re-sort the results of that search by date of publication. Sorting items by date means that the computer takes your original set of records, then re-sorts and lists them by publication date in reverse chronological order (the most recently published are at the top of the list; the oldest are at the bottom). This is helpful when you're only looking for the most recently published items; because they're at the top, you only have to look at a small fraction of the total results and are therefore "narrowing" your results.
In order to sort items (including books, e-books, government documents, pamphlets, audiovisuals, etc.) by date, you must first search the catalog. You may search using any of the methods available, but searching by subject, author or title are the most frequently used. Then sort those items by date by doing the following:
- Search the library catalog for all materials on your topic or by a particular author or title.
- Next, click the "Limit/Sort Results" button at the top of the screen, as illustrated in the top right of the screen shot below:
- Scroll down until you see the box next to "Sort results by year," highlighted in blue below. Click in the box beside it to place a check mark in it, as indicated in the screen shot below:
This will re-sort the list of results by publication date in descending order (the most recent at the top and the oldest at the bottom).
Limiting Your Search
Limit Your Search to Items in a Specific Location in the Library
You can limit your searches to a specific location in the library. This can help when you are trying to find a particular type of resource such as an electronic book, a government document, a children's book, a map, or a secondary school textbook. Instructions for doing this are listed below:
- Search the library catalog for all materials on your topic.
- Next click the "Limit/Sort Results" button at the top of the screen:

- Look for the drop-down menu next to "WHERE Item is located," highlighted in blue below, and click on the location of the item(s) you want to limit results to, as pictured in the following screen shot:
All the locations in the library should appear on this menu. E-Books are in the Electronic Books collections. Children's books in the Curriculum Lab are referred to as CL Easy Readers, CL J Fiction, CL J Non-Fiction or CL Young Adult. Secondary school textbooks in the Curriculum Lab are referred to as CL Textbook. (For help with other locations see the reference librarian.)
- After selecting the appropriate location, click the "Limit/sort items retrieved using above data" button found at the bottom of the screen.
Limit your Search to Textbooks in the Curriculum Lab
To look at all the textbooks held in Hackney Library, search the catalog by title, using "textbooks" as your search term, as illustrated in the screen shot below:
The results are listed by grade level, with the location "CL Textbooks" in bold, followed by a three-part call number separated by dashes, as seen in the following screen shot:
(For a more complete explanation of these "call numbers" for textbooks, see our North Carolina Textbook Codes page.) All K-12 textbooks are located in the Curriculum Lab in Hackney Library.
Limit Your Search to Videos
Videos are included in the library catalog. To find a video on a particular topic, you must first search the catalog by subject word to find all the materials on that topic. Then limit your results to those materials that are videos. Instructions for doing this are listed below:
- Search the library catalog for all materials on your topic.
- Next click the "Limit/Sort Results" button at the top of the screen:
- Look for the drop-down menu next to "MATERIAL type" and choose "PROJ MEDIUM" from the menu list, as illustrated:
- Next click the "Limit/sort items retrieved using above data" button found at the bottom of the screen:
This will retrieve only those items on your topic that are videos.
Other Ways to Search
Browsing by Call Number
Browsing by call number can be useful in locating books similar to those you've already found helpful. It's the electronic equivalent of standing in front of a bookshelf that contains a helpful book and looking at those shelved near it. Call numbers are the numbers on the spines of books, audiovisual cases, and other items in the library. They are assigned to items based on the topics they cover. Items with the same or similar call numbers treat the same or related aspects of specific subjects and are therefore shelved together.
To browse by call number, choose "call number" from the options given for searching the catalog, as highlighted in blue below:
Type in the call number of an item for which you'd like to find similar works; then click "Search":
The results are listed beginning with items having the call number you typed in. For more information about the item, click on the call number to see the full record, including its location in the library and its availability:
Searching Using a Partial Title
Even if you don't know the exact or the complete title of a book, you can still search for it in our catalog by doing the following: Instead of searching the library catalog by title, try searching by keyword and using what you think is the title as your search term. A keyword search looks in the title field of a record as well as other fields, but is more forgiving than a title search. You don't need to know the exact title, as long as you know some of the words. On the other hand, when you search by title, you must use the exact title to bring up a record.
See the following example of using a keyword (or word) search for the partial title "confederate widow" to find the novel Oldest Living Confederate Widow Tells All by Allan Gurganus:
Marking Catalog Records (To Email, Save, or Print Catalog Search Results):
Searching the catalog by any method (by subject word, author, title, etc.) produces a list of results or records. (If only one item is found to match your search, the record for that item is displayed rather than a list of records.) These can be marked selectively for printing, emailing, or saving by doing the following:
- Search the catalog by any method (subject word, author, title, etc.).
- Click to place a check in the square box in the "Mark" column to the left of each title you want to mark, as illustrated below:
- Click the "Save Marked Records" button at the top or bottom of the screen before moving on to any following screens of results, as pictured below. (Note: If you fail to save your marked records before proceeding to each succeeding screen, your marks will not be retained.)
- When you've finished marking and saving records, click on the "Export Saved Rec." button at either the top or bottom of the screen, illustrated below:
- Click on the "Extended Display" button at the top of the screen to see the locations and call numbers for each item:
- Check to make sure that you want to retain all the items in your list. (To remove items from the list, click the square box next to the items to be removed and then click the "Remove Marked Records From this List" gray bar at the bottom of the list. Those that you marked with a check will then be removed.) The following sample screen shot indicates that the first item will be removed from the list because it is checked:
- To print your list of marked records, choose "Print" under the "File" pull-down menu, or click the browser's printer icon, as illustrated below:
Your list should print as it appears on the screen.
- To email your marked list, click in and select the radio button next to "E-mail" (highlighted below in blue) within the "Send List To" box; then type in the email address to which the list will be sent in the "To:" field; then click "Submit":
If your email is sent successfully, you will get an "E-Mail Sent" message in red above your list, as illustrated below:
- To save your list (to either a floppy disk or hard drive), select the radio button next to "Local Disk" in the "Send List To" box; then click "Submit":
When you do so, a box will appear asking you whether you want to open the file or save it to your computer. Click "Save," and then navigate to the floppy (A: or B:) or hard drive to save it there. You can then open the saved file in a word processing or text program later:
- When you're finished with your marked list, click the "Clear Saved Rec." button; until you do so your marked records will continue to remain in the marked records list:
What If a Catalog Search Doesn't Provide the Resources I need?
Hackney Library offers a service called Interlibrary Loan to its patrons. If you need a book or a journal article that is not available in the library's collection, we will borrow it for you from another library. This service is generally free for books and articles. Please see our Interlibrary Loans page for more information.
