Evernote is free software allows you to easily capture information in any format irrespective of device used and makes this information accessible and searchable at any time. As Roy "Todd" Vandenbark mentiones it is very useful web 2.0 tool comes in versions for Windows and Mac computers, and many mobile devices including Windows Mobile phones, the iPhone, and iPod Touch. And Evernote organizes everything based on tags you add to each item, allowing you to search for items and group them into "notebooks." You can publish any of your notebooks for others to see, and once published, it will be given its own unique URL and indexed by search engines.
Evernote offers two service plans, free and premium. The free account allows you to upload up to 40 MB of information per month, and is limited to images, audio files, link files, and PDFs. Notebooks published from any free account will include advertising in the margin. For $5 per month, or $45 per year, you can upload up to 500 MB of information in any file type, and they are secure socket layer (SSL) encrypted for added security during transfer. In addition, advertising is turned-off for premium users. The Web site offers some documentation and searchable support, and it includes a number of helpful tutorials.
The librarians experimenting with Web 2.0 applications may try tools provided by Springshare.com through which libraries can distribute their content to other websites, blogs, and courseware systems. As mentioned on their website Librarians can use it to create attractive multimedia content, share knowledge and information, and promote library resources to the community. Academic, Public, Special, and K-12 School Libraries find LibGuides an ideal solution for subject guides, information portals, course guides, community guides, research help, faculty/teacher support, etc. But this is not free software.
