@Note is a collaborative annotation system developed under the auspices of the Google’s 2010 Digital Humanities Awards program. It is developed by ILSA (Research Group on Implementation of Language-Driven Software and Applications) and LEETHI Groups (Research Group on “Spanish & European Literatures: from Text to Hypertext”) at Complutense University (Spain). @Note tool retrieves digitized works from Google Books and, in particular, from the free-access UCM-Google collection. It lets the reader add annotations to enrich texts for researching and learning purposes such as reading activities, e-learning tasks, proposal of critical editions, etc. @Note promotes the collaborative creation of free-text and semantic annotation schemas on literary works by communities of researchers, teachers and students, and the use of these schemas in a very flexible and adaptative model for the definition of annotation activities.
