I was looking through a book which I had planned to xerox and return — and found that it was designed kind of as a workbook. I’ll have to buy it if I want to work with it, in-depth. I did, however, get the publication information and the call number, and it doesn’t look like it was on hold.
I also found a book on writing which was in the Biography section. It would not likely have been found, however, unless one ran a keyword search: neither of the subject headings had anything to do with writing. Unless one knew who Joan Frank was already (I did not)…they would just be lucky that the word “writing” was in the title, or depend on a fulltext search (which I believe my system has, but which is unwieldy at best).
Nothing else about this book makes it easily findable by browsers. The only reason I ran across it is that I work here and sorted it.
