Online Catalogue Searches

NLC's OPAC system is the major way to access library resources. We only introduce the search functions for rare books here. If you wish to receive more details on other categories of books, please click on the "user's instruction" button on the search page, as illustrated. If readers have specific needs, they can also enquire our librarians in the Reference Department.

 

 

Basic searches though OPAC

You can search the catalogue in the following ways:

(A) Title search: Enter the full or partial information of a title. For example, for an English document, you can omit the initial letters"A', "An" and " The" .

(B) Keyword search: This is a more effective way to search. It can search in adjacent words, thus provide more precise search results.

(C) Author search: Enter the following phrases to search: Name of the author (individuals): You can enter the author's full name or keyword. For foreign authors, enter the last name first and then the given name. You can switch the last name and the given name if you are not sure which is first. Name of an institution: Enter the most commonly known name of an institution. Name of a conference: Enter the name of a conference to search for articles from the proceedings.

(D) Whole field search: Users can also search the catalogue with whole phrases, to find the most complete result. However using this way, you may end up with excessive search results.

3. User's Instruction of Card Catalogues

Besides the e-catalogue, there are also sets of card catalogues in each reading room for readers to browse. Since bibliographies of certain books are yet to be available for online retrieval, the bibliographic card is a very important tool for book retrieval.

The card catalogues of the Ordinary Ancient Books Section, NLC Library of Ancient Books can be browsed by classifications, titles, and authors. We use the Liu Guojun Classification to arrange the books into fifteen classifications.

The bibliographic cards for ancient books in the Rare Books Reading Room are browsed by classifications, titles and authors. The classification method we use is the Four-Branch Classification for ancient records. The rubbings bibliographic cards are browsed by titles, authors and by regions. Using the browsing by regions method, readers can find information of a rubbing by searching for the location of the original inscribed stone.
