JSTOR's new interface made searches default to covering their entire database - so results might include articles students didn't have access to on JSTOR and which wouldn't even be linked via OpenURL to the library's subscription in another database. (Meredith Farkas describes the problems neatly.) Librarians complained loudly on blogs, JSTOR's Facebook page, and elsewhere, and a day later JSTOR has announced that they'll change the default while they continue work on OpenURL.
WolframAlpha has added widgets that focus on a specific kind of data and can be embedded into a webpage by copying and pasting the code. Categories cover all kinds of subject areas - some widgets might be relevant in a subject guide. (You'd need to add a new rich text box, then select the plain text editor and copy/paste in the embed code from WolframAlpha.)
Librarian as resource
University of Michigan Library's search results now bring back subject librarians as well as relevant databases, catalogue items, subject guides, institutional repository hits, and external websites. Their blog about this links to some examples.
eBooks and compatibility
Jason Griffey writes a clear explanation about why ebook filetypes and digital rights management means that purchasing an ebook doesn't mean you can read it on any old e-reader.
Cooke, R., Rosenthal, D. Students Use More Books After Library Instruction: An Analysis of Undergraduate Paper Citations College and Research Libraries (preprint)
(They compared classes which received library instruction with identical classes which didn't.)
"In Fall 2008, students from first-year Composition I and upper level classes at Florida Gulf Coast University participated in a citation analysis study. The citation pages of their research papers revealed that the students used more books, more types of sources, and more overall sources when a librarian provided instruction. When these results were compared to those produced by students in upper level classes (all of whom received instruction), it was discovered that as the class level increased, the number of citations and the percentage of scholarly citations generally increased and there was a high preference for books from all disciplines, especially history."
