DIALNET

DIALNET is the database of the University of La Rioja, Navarra. This is a link to access to it: http://dialnet.unirioja.es/

In this database you can search for:

• Journals.
• Thesis.
• Congresos

 also, you can search in general.

You can select diferent fields of search like:

• Authors or Title. 

                With the information of this field you search for:

1.  Magazines articles.
2. Thesis.
3. Books.
4. Articles of collective works.

• ISSN Code or dIALNET Code.

You can´t search for articles combining the four fields or combining Title and Authors, so it is not a very good system of searching in my opinion. It is not very recommendable if you want to apply different filters or fields of searching.

I don´t recommend this database if you want an exhaustive searching.

DERWENT

Derwent is a database specializaed on patents. In this database you can find information about patents of all kind, with their respectively information, like the inventor, the patent code, the date of the patent...

You can search  in Derwent applying different search fields, like inventor, patent code, date... Also you can search using a thesaurus.

You can access to Derwent fron the web site of the libray of the UC3M: from the WOK (Wed Of Knowledge), web site which you can find in Universe-e of the library of the UC3M. Also, ou can search Derwent with a search engine.

The following is a direct link to Derwent:

With that link you look for patents in Derwent from the web site of WOK, but you have to be registered like an user of UC3M. So the better is search, for exapmple on Google, for Derwent.

OPAC

What is an OPAC?

An OPAC is an automated catalog of online public access library materials. Generally, both the library staff and the public have access to it in several terminals within the library or from home via the Internet.

The OPAC is often part of an integrated library system.

It is not exactly a information resource, but you can get from an OPAC information about articles of your interest. For example, you can get in which lbraries it is aviable to read it, or you can get some extra information interesant for you like year of publication.

An example of OPAC: WorldCat.

At present, some 30,000 libraries have bibliographic records from OCLC's OPAC, called WorldCat, a catalog of library materials with the collaboration of public and private libraries throughout the world, especially in the U.S.A. and Canada.  

WorldCat shows how many libraries have the same book or material. WorldCat users must connect their own library OPAC to see information from other libraries. The OCLC WorldCat is not technically an OPAC in itself, it is better called as Macro OPAC, is a bibliographic database used primarily by library staff (librarians) of the institutions that have an annual subscription to OCLC services. It is not used by users or the general public unless your local library subscribes to serve the OCLC FirstSearch reference. 

How can you find it?

You can find WorldCat from the institutions that have an annual supscription to OCLC services.

It is also searchable by search engines like Google and Yahoo, searching for "OCLC WorldCat Open".

RefWorks

RefWorks is not a database or any information resource, but I think that it a very interesant tool for students.

RefWorks is a web tool which make for us a bibliography, with a very good presentation. You must give some information to the program, like titles, authors, editorials, year of publication; all related to the books, journal or articles in general that you want to introcue in your bibliography. Then you have to select a format for the bibliography, there are a lot of possibilities, so there is at least one that is of your liking.

After that, the program works, and when it finishes, you have a good biliography on a .doc document, with your articles and format selected.

You can find it on the website of the library of my university, UC3M. When you enter, you look RefWorks on e-Resources. You click on the link.

The link of the web site where you are at the end is the following:

https://www.refworks.com.strauss.uc3m.es:2443/refworks2/?r=authentication::init&groupcode=RWUCarlosIII

You need an account to use RefWorks.

Database INSPEC

It is a scientific database, where you can combine different fields for search articles, like topic, author, title, year published, etc. Furthermore, INSPEC has a advanced search to search in a more especific way articles.

It is very useful for people who study something related with science, like a degree on ingeenering, or maths or physics.

You can access the database from the web of knowledge from the web site of the library of my university, the UC3M.

 It is interesting for my bachelor degree because I can find good articles about subjects like physics, linear algebra, electronical devices, chemistry.

The way to access into INSPEC is the next:

Google> UC3M> Library> Universe-e> Subject: Engineering> Link to INSPEC

There is a link to the web site of INSPEC: http://ip-science.thomsonreuters.com/es/productos/inspec/

If you click on that link, you must click on a link on the web site that is Web of Knowledge. Then you must be registered to use INSPEC.
