It should come as no surprise that, given Loligo's involvement in biological research for the past century, there is a large volume of scientific literature available on this animal. As the Internet develops, more of this information is available via the Web and other mechanisms. At present, most of the actual articles and publications are not available in this format. This is changing as more publishers are making the full text of their articles available on-line, often at a price. More commonly, references to articles are available in large, searchable databases. These references often contain abstracts as well as the title, author, and publication source so that the reader can form an opinion on the article. Often there is a means to request a copy of the article.
