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".

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.

Search engine

A search engine is a computer program that searches documents, especially on the World Wide Web, for a specifiec word or words and provides a list of documents in which they are found.

Some examples of search engines are the following next:

Altavista, Yandex, MSN Search, Teoma, Info.com, Google, Ask.com, Bing, Yahoo!, AOL Search, GoodSearch, Volunia, etc. There are multiple engine search more, but some of them are closed o inactive.

Some of the most important and best known are Google, Altavista, Bing, Yahoo! and Ask.com. I will talka bit of some of them.

Google has been estimated to run over one million servers in data centers around the world, and process over one billion search requests and about twenty-four petabytes of user-generated data every day.

Altavista was once one of the most popular search engines but its popularity declined with the rise of Google. In May 2011, Yahoo! shut down the site. Presently, the AltaVista website is up, and it is stated on the website that they are using the Yahoo search engine. Search results remain on the AltaVista pages.

Bing was formerly Live Search, Windows Live Search, and MSN Search is a web search engine from Microsoft.
