As in other international scientific gatherings to which we have previously referred, our interdisciplinary approach to information has also been argued within the information-systems arena of Ibersid (October 6-7) and the philosophical forum of SEFA-2010 (October 14-16). As in other occasions we pursued, on the one hand, strengthen our methodology and scientific soundness; on the other hand, disseminate our proposals. 

In Ibersid (15^th International Conference on Information and Documentation Systems held in Zaragoza, Spain, October 6-7) BITrum was presented as a virtual research community with a twofold focus: a scientific programme aimed at searching for a better and interdisciplinary understanding of information, and the internationalization of the virtual research community by means of a electronic infrastructure to be developed under international support. The communication, presented by José María Díaz in a session on knowledge organization, corresponds to a paper co-authored with Leticia Barrionuevo (s. paper-preliminary versionre attached; s. presentation). 

Among the contributors to the conference there were a significant participation of Latin America researchers (around the half of the contributions). Relevant in number and contents, the works presented covered the fields of: information and documentation systems (in general and specialized to education, organisations, and heritage), content analysis, legal challenges, information divide, and information retrieval (s. Programme).

• Prof. Javier García Marco (Universidad de Zaragoza, Spain), director of the event and editor of the Journals "Ibersid" and "Scire" was interested in keeping in touch with the group for eventual cooperation.
• Prof. Carlos Cândido de Almeida (Universidade Estadual Paulista, Brasil, and Doctor in Information Science), who presented a interesting work arguing for a semiotic- and pragmatical Peircian view on knowledge organization, showed his interest to our project and to collaborate with glossarium BITri. 
• Alejandro Uribe Tirado (Universidad de Antioquia, Colombia), who presented a contribution on digital divide and coordinates the Colombian chapter of the INFOLIT project, has been following BITrum activities and also showed interest in collaborating with them. 

The conference also represented the opportunity to meet with some other BITrum colleagues attending or contributing to the conference: Emilia Curras, Josefa Gallego, María Luisa Alvite (who presented a work in legal information systems). We therefore are in gratitude to all ibersid organisers for bringing about this occasion.
