The Library search tool
The library search tool is a good place to start searching. Here you can search either under the tab "Books and e-books" or under "Articles".
Books and e-books
When you search for books and e-books with the Library search tool, you are automatically redirected to LIBRIS, the national catalogue for Swedish libraries. Note that the search is restricted to Luleå University of Technology, but you can remove the restriction if you want to see if a title exists in another library. As an employee of Region Norrbotten or as a medical student at Sunderby sjukhus, you have access to e-books marked with the text "Medical e-library, digital resources". However, if it says "Luleå University Library, Digital Resources", you do not have access to the e-book.
In the Library search tool, under the "Articles" tab, you search in several databases and journals at the same time, and that means you might get a large number of hits. In that case, it might be better to use a subject database instead, where you can make specific definitions.
A database is a collection of materials which have been made searchable. It can cover many subjects, or be subject-specific, thus collecting just those materials in a specific discipline.
Some databases contain full text materials, while others provide only references. They may also contain factual data such as statistics, standards and patents. It is good to find out what type of material you can find in the database.
In a database, you can often narrow your search in other ways than you can in the Library search tool. For example, you can limit your search to a specific age group or geographic area. Databases work in different ways so it can be a good idea to look in the database help section to get more detailed information about how you should proceed when searching the database.
If you search with Google you will miss out on a lot of scientific material. Therefore, it is often better to use the library search systems and databases. You can also use the service Google Scholar to find scientific material. All the material in Google Scholar is not scientific, and the selection criteria are unclear. It is therefore important to critically examine the sources.
