FirstSearch offers a precise full-featured way to search the WorldCat database. It is primarily designed for library staff, researchers and expert searchers. The array of limits enables the searcher to screen out unwanted items and locate exact titles, additional formats and/or content. With FirstSearch, you will have a comprehensive view of your library holdings or holdings of libraries worldwide. FirstSearch is a great tool to help you address reference questions, make collection development decisions and meet your interlibrary loan demands.
This course is for library staff who want to refresh their searching skills in FirstSearch or those who are new to the service and want to explore the functionality available within it.
This course does not provide directions for customizing FirstSearch. For this information, please consult the documentation, Manage FirstSearch and the WorldCat Admin, found on the FirstSearch support site.
Note: This learner guide is designed to accompany the Searching WorldCat in FirstSearch course.
FirstSearch offers three search screen options. The recommended search screen depends on the information you or your patron have and the results sought.
The Basic Search enables you to search a few of the main indexes in a database. Use the Basic Search if you need quick results using a simple search statement. The BOOLEAN operator “And” is understood between these indexes.
The Advanced Search enables you to construct more complex search statements and to apply filters.
The Expert Search is designed for experienced searchers who prefer to enter logical search statements. A list of indexes and labels is provided in a single drop-down list. For example, to search for items by Barbara Kingsolver that do not include the term “vegetable” in the title, enter the index label for Name (au: ) and then enter the term “vegetable” with no index label. Instead, select the title index from the drop-down list. The title index label will apply only to the unlabeled term “vegetable”.
Reference information for constructing searches displays at the bottom of this screen.

FirstSearch has no limit on the number of records returned from search. Setting search limits is a good way to narrow these results. Options include year, language, number of libraries (library holdings), and document type.
| Limit to Date Option | Format |
|---|---|
| Single Year | YYYY |
| Open date range | Enter YYYY- ; 2010-2014 ; >1999 ; <1980 |
| Specific date range | Enter YYYY-YYYY |
| Greater than specific year | Enter >YYYY |
| Less than specific year | Enter <YYYY |
Document types classify items by format. These may be used to limit search results to a specific document type (bibliographic format). Hover over the type name to see what is included in that type.
| Document Type | Includes |
|---|---|
| Books | Books, pamphlets, technical reports, manuscripts and other written works. |
| Computer files | Computer software, numeric data, interactive multimedia, etc |
| Internet resources | Websites with online documents, graphics, systems or services |
| Maps | Maps, map manuscripts, globes, and other cartographic material. |
| Serial publications | Periodicals, newspapers, annuals, journals, |
| Musical scores | Printed music materials, including full score, choirs score, close score, etc. |
| Sound recordings | Both musical and non-musical sound recordings. |
| Visual materials | Projected media, Two-dimensional non-projected graphics, artifacts or kits |
Further limit your search results by audience, content, and/or format.
| Sub-type | Includes |
|---|---|
| Audience | Juvenile or Not-juvenile |
| Content | Fiction, non-fiction, biography, thesis, Biography, music, non-music |
| Format | Subtypes of document types, such as DVD, VHS, Large print, Braille, etc. |
| Limit type | Function |
|---|---|
| Items in my library | Limits to items held by my library |
| A specific library (add OCLC symbol) | Limits to items held by another library's OCLC symbol |
| Shared print commitments only | Limits to items with shared print commitment |
Use ranking (before you search) to organize the results of your search. Available ranking options vary by database and may include ranking by relevance or date. Ranking by number of libraries holding the item is also available in WorldCat.
Searching WorldCat Indexes provides comprehensive information about indexes used to retrieve records from WorldCat. OCLC services, including cataloging and discovery/reference, use the same search indexes. Additionally, it shows MARC fields and subfields indexed for each WorldCat index, gives examples, and provides information about how each index works to help construct searches that retrieve the records you need.
Use wildcard and truncation symbols to expand or focus searches. The system retrieves up to 300 matches to search terms when you use wildcards or truncation.
Note: For non-Latin script search terms, truncation can be used for Bengali, CJK (Chinese, Japanese, and Korean), Devanagari, Tamil, and Thai scripts only. For other supported non-Latin scripts, use browsing for automatic truncation.
| Name | Symbol | Function | Usage | Example |
|---|---|---|---|---|
| Plurals | + | Wildcard |
|
mammal+ retrieves mammal and mammals wax+ retrieves wax and waxes |
| Number sign | # | Wildcard |
|
wom#n retrieves woman and women |
| Question mark | ? | Wildcard |
|
encyclop?dia retrieves res?4tion retrieves respiration, restoration, reservation, etc. |
| Asterisk | * | Truncation |
|
connect* retrieves connect, connection, connectivity, etc. |
You can view expanded metadata in each entry, which can help you select individual items to view. The search results are unclustered so all records that match the search terms are included in the result set. These results can be limited and filtered once displayed. Furthermore, you can see results for related subjects and/or related authors.
After performing a search, click the Save Search link on the Results screen to save your search results. Those search results can then be re-used when you click the Previous Searches link on the FirstSearch Search screen.
