Today I finally went back through old blog posts, located ones on book digitization, and added a label to them (book) that will allow them to be found more quickly. I did think because I do receive emails and phone calls about book digitization, and I wanted to be able to point people easily to a group of blog posts on the topic. Did I find every blog post that should be in this category? Likely not, so I'll try to find time to skim back through the blog and recategorize more posts.
BTW this did mean that I had to create a new label for "book recommendations," which might get more things added to it, too.
One of the things I learned at Internet Librarian in October 2007 is that we generally do not use enough tags (post). And although I know that I still not do use enough tags, I have to admit that it can be time-consuming, since I use both labels (a feature of Blogspot) and Technorati tags. And do you really want a ga-zillion labels (categories) on the left side of this blog?
