Once again we are giving out information about on-line resources, which may be personal pages, blogs, institutional portals etc. We will grant special attention to those that are easy to use and, preferentially, free to access. A substantial part of these will be dedicated to medical sciences.

Bring us your suggestions and comments!

WolframAlpha
It has already been stated about WolframAlpha that it may become as influential in our work as Google. It is a computational knowledge engine developed by Wolfram Research.

WolframAlpha presents systematically organized information, intending to respond directly to the search questions and expressions introduced, as opposed to being a mere set of not always relevant pages and resources, as happens with the conventional search engines we know.

Popular Science magazine voted WolframAlpha the best innovation in this area in 2009

Página do Centenário da Universidade de Lisboa 
This is the page of the Centenary of the University of LIsbon. Here one can find varying information topics, among which we highlight the electronic encyclopaedia Memória da Universidade, Memória da Universidade, a Project that now has many entries and is permanently being updated, according to the Wikipedia format, by a broad group of collaborators.

As one can read on the page, Memória da Universidade is the prototype of an electronic encyclopaedia of teaching, science and culture in the history of the University of Lisbon, which will function as an integrating and synthesis element for the commemorative activities of the Centenary of the UL within the scope of the History and Heritage of the University.

Indeed, this is a re-founding of the university by the republican regime, given that the founding of the UL dates back to the XIII century.

Dicionário de Termos Médicos 
The Porto Editora Dicionário de Termos Médicos, which is part of Infopédia, was drawn up by Manuel Freitas e Costa, Full Professor (retired) from the Faculty of Medicine of the University of Lisbon.

Characteristics: about 30,000 concepts from medical vocabulary, information about the origin of the words, medical terminology associated to the name of about 4,000 figures from different areas, who have identified or described diseases, signs, microorganisms, techniques or therapies, exhaustive coverage of medical terminology.
