The catalogue is a search and discovery tool that provides results from the library's online and print collections in a single search. It includes titles of printed books, journals, manuscripts, letters, and other material available at Leiden University Libraries (UBL), as well as links to the full-text of millions of journal articles and digital images of prints and manuscripts.
- The catalogue does not contain a large number of Dutch journal articles. To find articles in Dutch, it is advisable to consult the subject guide Searching Dutch Articles (only available in Dutch).
- To find more journal articles, also search subject specific databases, available through ‘Find Databases’. More information can be found in the subject guide for databases.
Performing simple searches
The easiest way to search the catalogue is to type one or more keywords and click the Search button. When searching for an article, choose All Content; when searching for a book from our collections, choose Leiden Collections. The catalogue searches for items regardless of capitalization.
What is being searched?
All Content is searched by default, here you will find: (e)-books, (e)-journals, (digital) articles, audiovisual material and Special Collections. You will find the contents of Leiden Collections and Special Collections, but also digital articles from databases and the Leiden repository.
In Leiden Collections you will find both digital and physical materials available at Leiden University Libraries and the Special Collections. You will not find individual articles here, however. You can choose to either search in all library locations or in a library location of your choice.
In Special Collections you will exclusively find the rare materials in the Special Collections department of Leiden University, such as manuscripts, early printed books, prints, drawings, letters, archives, photos and maps.
Use the Advanced Search option to search commonly-used fields, combine search options or limit your search by material type, language, or publication date. For instance, use the field Author/Creator in comination with is (exact) to find all available sources by a specific author.
More specific searches
Searching for a phrase
To search the catalogue for a specific phrase, place quotation marks around the phrase. Use the double quote marks, not the single ones. For example: if you search for "global warming" you will only find publications that contain both these words in this exact order.
Combining search terms
OR: Use to search for items that contain at least one of the words or phrases you typed in the search box. For example: Irish OR Celtic will find items that only contain the word Celtic, only contain the word Irish or that contain both words.
NOT: combining search terms with the NOT operator narrows the search by excluding unwanted terms. For example: Celtic NOT Irish will find items that contain the word Celtic, but exclude items that contain the word Irish.
Note: To use OR and NOT, type them in all caps.
Include records with no full text access
By default, this filter is unchecked, and can be found among the filters after searching. When it is checked, you will also receive titles in your results that are not available via the Leiden University collection and of which only the bibliographic information is available. These titles may be available in other libraries. To request material that is not available in our libraries, see the webpage: Can’t find it at UBL.
Searching for printed items
If you only wish to search for printed items, please filter your search results: under refine my results > availability, choose Physical Items.
Material can only be requested when you are logged into the catalogue. You can log in using your ULCN- (library)account. Click the Request-button and choose your pick-up location. Please find more information on our webpages on borrowing.
When under Loan Policy the catalogue lists library use only, reference only or not loanable, the item can only be read within the library.
Books in the reading rooms
Part of the collection is located in the reading rooms. These items are not loanable. Click the Locate button to find in what reading room the item is shelved.
Renewing and returning
You can return borrowed books at any of the UBL library locations. Books will be renewed automatically for a certain period of time, unless someone else reserves them. Please find all information and policies on our webpage on renewing and returning.
Remote access to digital material
Anyone can search the catalogue to consult which material is accessible through Leiden University Libraries anywhere. Login is not required for this.
Only Leiden University and LUMC students and staff have worldwide access to full-text articles, after logging in. Guest users and Leiden University alumni only have access to full-text digital material within the university network. Alumni can access some of our databases via the Leiden Alumni Databases website.
Notable exception to this rule are e-books hosted by ProQuest, which are only accessible to Leiden University students and staff, regardless of the location.
Most of the e-books Leiden University Libraries gives access to can be found by their title in the catalogue. You can refine your search results to only show e-books: under Availability, select online access, then select (e-)books under Resource Type.
More information: how to use e-books.

No online access
