From abstract to full text

CAB Abstracts banner icon Global health banner iconMost people searching an abstracts database want to be able to click straight through to the full text of a relevant or interesting abstract.

Full text availability is one of the real added value features of CAB Abstracts and the Global Health database, but where and how to find the full text can still be confusing.

Here at CABI we do try hard to make the full text of any paper we abstract for the database(s) available to users by providing links (including DOIs where possible) and holding full text in our own permanent repository. Over the years we have been building a repository of full text material, mainly journals and conferences, which we host on our servers so that users can click through directly from the abstract straight to the full text pdf. The CABI repository currently contains over 85,000 full text papers from scientific journals and over 54,000 full text papers from conferences, plus the full text of a number of reports and single documents. If you search CAB Abstracts or Global Health on our own platform (CAB Direct), all papers held in the CABI Full Text repository have a clearly visible “View Full Text” button. The CABI Full Text repository is also available to searchers using other platforms (e.g. OvidSP).

We created the CABI repository so that we could offer permanent, unbroken links to full text papers from journals and conferences which for some reason or other are not available online or are difficult to find –  some papers, for instance, are available in print only, and some are available online but the links change or websites disappear over time. The initial concept was to provide a win-win situation for authors and users – authors knew that their papers would be more widely disseminated and read if they were accessible through our widely used database, and users would be able to click straight through to the full text. Our aim was to improve access to papers which were ‘difficult-to-find’ i.e. those which were not easily accessible through open access systems or from mainstream sources with a strong web presence.

Once you’ve done your search, here are some suggestions for subscribers on how to access the full text paper or document from an abstract or bibliographic record on the CAB Direct platform (this is generally applicable to CAB Abstracts/Global Health on any platform):

(1) If the abstract has a “View Full Text” button, this is a link to the paper in the CABI Full Text repository (for advanced users, sc:ft in the search box will pick up all records with a full text document in the CABI repository).

(2) If a url is provided on the database record, click on this to go to the publisher or society website. If your institution has a subscription to the journal, you should have access to the full text. If not, you’ll still find that some of these documents may be open access. Some publishers make all their papers open access, others make special issues open access, sometimes within the same issue of a journal some of the papers will be open access and some not. Others apply an embargo, so that papers published before a certain date become open access. All these models change frequently and the only certain way of knowing whether the full text is available (either open access or paid for) is to try the website.

(3) If the abstract record has a DOI this is even better. The DOI (Digital Object Identifier) is a unique identifier for that paper. Clicking on the DOI will take you straight to the exact document. Try copying the DOI into your Google search box to see if the paper has been deposited in an institutional or other repository.

(4) Or you can contact the author directly – most recent records have email contacts.

Finally, if you are a conference organizer, editor or society and wish to see your papers held in our repository so they are easily accessible to a worldwide audience of subscribers, please contact our Full Text Coordinator.

Veterinarians Target Next Virus for Eradication

 
Following the recent eradication of rinderpest virus in cattle (see blog), the veterinary profession is contemplating which viral disease of animals should be targeted for eradication next. This is not an easy task considering the vast number of viral diseases that plague livestock animals and have devastating effects on animal health, public health and people’s livelihoods.

Sheep

According to the authors of a scientific editorial (1) and a review article (2) that appeared in the recent issue of Veterinary Record published on 1st July 2011, the next livestock virus targeted for eradication could be peste des petits ruminants (PPR) virus.

Dr Michael Baron and colleagues from the Institute for Animal Health (IAH), Pirbright, UK said in their review that the Food and Agriculture Organization (FAO) and the World Organisation for Animal Health (OIE) should focus on PPR virus as the next livestock virus for eradication.

PPR virus affects sheep and goats and is closely related to the recently eradicated rinderpest virus. Cattle can also be infected with PPR virus but they do not show obvious signs of disease. PPR is circulating on the edges of the European Union, on the southern shores of the Mediterranean. Outbreaks were reported in Morocco and Tunisia in 2008 and there is evidence for its presence in Algerian sheep this year. It has also been present in Turkey for many years. PPR is the fastest growing and one of the most economically important diseases of sheep and goats, the animals that play a very important role in sustainable agriculture and development in Africa and Asia. Mortality in infected animals ranges from 10 to 90%, depending on age, breed and secondary infectious agents. Animals that survive become anorexic, their milk yield is reduced, and they are susceptible to secondary infections and abortions.

Baron and colleagues are already working on the development of a “smart” vaccine for PPR, one that leaves an antibody signature different from that created by infection with the virulent virus, so that vaccinated animals can be distinguished from animals that have been infected by virulent virus, and vice versa. They are also working on a "dip stick" test for PPR virus, similar to the one that IAH developed for the rinderpest eradication programme.

There are good reasons to believe that the eradication of PPR is an achievable goal, because the PPR virus shares a number of properties with rinderpest virus that contributed to the successful campaign to eradicate the latter, i.e. there is a safe and reliable vaccine; simple and effective diagnostic tests are available; the virus has a short infectious period, with no carrier/persistent state; transmission occurs only by close contact; and there is an economic incentive to eradicate it.

However, before a massive commitment of national and international resources for a successful eradication campaign, which would require surveillance and monitoring over a long period, a thorough evaluation of the likelihood of success of an eradication campaign, as well as its costs and benefits, is of utmost importance. Potential for eradication of other diseases such as foot and mouth disease (FMD) or rabies virus, for example, also needs to be evaluated.

CAB Direct database offers an excellent source of scientific information and is a very useful tool for evaluating potential for eradication of any viral disease of animals. It comprehensively covers world’s scientific literature from over 150 countries and in over 50 languages on all the viral diseases of animals, including PPR, FMD and rabies. CAB Direct database contains over 17000 records on rabies, over 13000 records on foot-and mouth disease and over 800 records on peste des petits ruminants.
