Q: Does the Ovid search platform offer access to the CAB Thesaurus and, if so, how is it used.
A: The CAB Thesaurus, on the Ovid search platform, is found under the “Search Tools” icon on the Advanced Search page. This takes you to the “Select a Tool to View” page, where you will find three options to search the Thesaurus along with an option to browse/search the CABICODEs. Select the “Permuted Index” option, type in a single search term, such as Nitrogen, and then click the “Perform Search” button. This will display a page that shows all the Thesaurus terms that contain the search term (this is the Permuted Index) and, for each of these terms, it shows all the related Thesaurus terms. You can select terms to search by checking the “Select Term(s)” check box to the left of the term. In addition to checking the “Select Term(s)” check box, you can also check the “Explode” check box. By doing this, the resulting search will search for the main term (e.g. Nitrogen) plus all its Narrower Terms from the Thesaurus. Once you have selected all the terms of interest, simply click the “continue” button to execute the search.
From the Permuted Index screen, you can also drill down in to the Thesaurus by clicking on any term of interest. This will then show a hierarchical Thesaurus entry, for the term of interest, along with Broader and Narrower Terms one level up and one level down. Again, you can check the boxes for the term(s) you want to search and you can use the Explode function to include all the Narrower Terms in your search. Terms in the Thesaurus may have several levels of Narrower Terms below them. Clicking the “Explode” check box will search for all the levels of Narrower Terms. If, for example, you don’t wish to search for Nitrogen fertilizers and all its Narrower terms but, instead, you want only Ammonium Fertilizers plus its Narrower terms, simply click on the term “Ammonium Fertilizers” to display its hierarchy, and continue as described above, using the Explode function if required.
Ovid also make use of the CAB Thesaurus through the "Map Term to Subject Heading" function that is available from the Advanced Search screen as a check box. If this box is checked then, each time you search for a term, you are presented with an intermediate search page that lists all the terms from the Thesaurus that contain the search term entered. This screen can be used in the same way as the Thesaurus search tool detailed above. Note: If you search for multi-word phrases, the list of choices will be much smaller and, if your search term is not a Thesaurus term, you do get some very strange terms in the displayed list,. The mapping function is a very useful feature suggesting additional terms that you may want to include in your search strategy.
Q: If a user has CAB Direct, do they need to take Global Health as well?
A: At the moment, the CAB Direct service provides access to a single, combined database that incorporates CAB ABSTRACTS and Global Health. If they lease CAB Direct, they wouldn't need Global Health as well. However, if they are only interested in the Medical/Human Health data, we do make Global Health available as a separate database for a lower fee. Global Health uses the same search software as CAB Direct.
Q: What is CABI's policy on remote access?
A: Remote access is automatically included with any network lease of a CABI Internet service. However, remote access is strictly limited to dial-in access by enrolled students and/or permanent staff belonging to the subscribing Institution.
Q: Does CABI offer unlimited access pricing?
A: Yes we do, but it is not generally advertised. Requests for unlimited access should be discussed with the appropriate CABI Regional Manager before any quotes are given.
