The BUBL menu bar at the bottom of the page allows you to move directly to any other BUBL service, without having to retrace your steps. Help Help is available throughout the service as appropriate. All help information is accessible via the Help option in the top menu bar, while the search help is available directly from each of the search screens. Search Everything on LINK is catalogued and can be accessed through the Search option. Catalogue fields include title, author, subject, abstract and class number.
Boolean combination is available, as is truncation.
Additional non-LCSH subject terms are provided where appropriate to assist retrieval. To the browser, the LINK service is organised as a series of subject libraries in Dewey Classification order. It's rather like browsing the library stacks. In addition, a set of more flexible and in some cases more meaningful subject headings are offered, in alphabetical order. These provide an alternative method of locating exactly the same information.
