As someone with 200 books within arms reach of my desk, without counting those in the bookshelf behind me, I obviously have a fondness for the written word. When reading a particular text closely however, what advantages are there to an electronic format over a physical format? While portability of an electronic text is often cited as an advantage, as the ereader can hold multiple books in a relatively small space, I believe that the true strength of an electronic text is the search functionality. With proper bookmarking, one can quickly refer to key sections of the text, and search for other similar passages.
This isn't really a new technique. Many popular academic texts have comprehensive indices and supplementary notes, and with a little work, one can mark passages in any physical book for later reference. In some ways, this actually helps one understand the text at a deeper level, as it requires a deeper engagement with the text.
Another key aspect of using an electronic text is an easy way to mark up the text, and make meaningful notes. While I don't usually mark up fiction I'm reading for fun, my academic texts have lines underlined, words circled and squared, and margin notes. This is something I've started recently, especially for passages I'm trying to more deeply understand.
If I was studying a book with an electronic edition, it would be great if I could highlight, or otherwise mark up the text, and have my selections exported to my word processor for essay writing, with full citation support in whatever format I require (MLA is the citation format I most often use for writing in the humanities). I would love for the pagination of the online version to reflect a print version, even if it is displayed in a different format on the device. Sadly, not all texts are available in ebook format, and when they are, there are often regional restrictions on availability. Robert Fagles' contemporary translation of The Odyssey is available on Amazon.ca in print, but the Kindle edition on Amazon.com is unavailable to Canadians. A sad state of affairs, and not likely Amazon's fault, as there are licensing restrictions put in place by the rights holders.
I'm pleased that a number of scholarly presses and consortiums are planning changes and advances in etext publishing, as reported on sites such as Library Journal. I'm generally pleased by what I've heard about these initiatives, I only wish they were available now.
