DICE Final Report Google Scholar see http://scholar.google.com Figure 12. Details from one of the returned results Any assessment of RD services would be bound to mention those available through Google. Readers will almost certainly be familiar with Google Web Search, but a variety of more specific search services are now available (see the ‘more’ link from the Google home page). These services can access the latest News, Maps, and Images etc. Which have been made available on the web; there is also a service to access the full-text of certain Books or further information from publishers and booksellers. We focus here on the Google Scholar service because it has a particular educational focus. ‘you can search across many disciplines and sources: peer-reviewed papers, theses, books, abstracts and articles, from academic publishers, professional societies, preprint repositories, universities and other scholarly organizations’. Scholar offers a range of useful search-related services and features which we can’t describe in detail here, but they include locating (resolving) articles, papers etc... Through its library links program or where the library has its holdings listed with a particular registry. Even assuming these services are not available, relevant quality articles are often available in full text via the web, albeit one might first have to check through and ignore several links the full-text of which might only be available to subscribed users. (The service is also useful to publishers in promoting their content: they are required to offer access at least to abstracts). The search interface allows for simple and advanced searching, not dissimilar to those we have already discussed. Figure 13 shows results returned for a search and one can see that for each there are title, author, publication date and journal details given and the opening lines of text; the title is also the web link to the article. Usefully too there are links to other papers that have cited the listed referenced article and related web articles (web search). With regard to saving particular results of interest from the returned list, it looks like there is no special provision for this (at this time) excepting the use of the book-marks facility of the browser used. 44
There’s a link to Google Scholar from the project website. DICE Final Report Figure 13. Results returned using Google Scholar GetRef see http://edina.ac.uk/getref/ GetRef 13 has been available for several years now as a service from EDINA, the JISC-funded national datacenter in Edinburgh. From the name of the service, one might guess that it searches mainly (Abstract and Indexing) databases to return references, but it will support protocols to search other web resources and results are returned in a format (OpenURL) that can be used with institutional link resolvers. Users require an Athens account to use the service, available to the UK higher and further education community. It is somewhat more complicated than the other tools we have looked at in that it offers federated searching – search queries are passed to multiple targets simultaneously 14 . This makes for a more 13 GetRef developed from earlier projects in cross-searching (x-grain) and broker services (zbalsa). See http://edina.ac.uk/projects/joinup/zblsa/cel/ for a useful presentation explaining key ideas in resource discovery. 14 The service is currently configured to search a small number of targets which makes searching easier, but EDINA will customize the interface according to each institution’s requirements including searching of local library databases. There are hundreds of potential targets available, listed via a link at the home page of the web site. 45
