From this list, there are many journals and magazines that will be in turn connected to book publishers. Contact these publishers directly, request sample copies of current periodicals or review copies of related books, and ask about submission guidelines. Publishers like working with librarians, and for this reason you can leverage your position to access the kind of information you need to improve your chances of being published. Maintain realistic expectations. Most professional and technical publishers, and this includes library and information science publishers, keep costs down by maintaining low stocks of books.
Technical books tend to be expensive and often have relatively small potential audiences.
Don't be too surprised to discover that your publisher will only print 1000 copies of your book. As a result, you will make about ten per cent royalties off the price of each book sold. It's not a lot of money, and if you were expecting something more grandiose, you might be disappointed. However, if you keep your expectations focused on professional development, then all the work you put into it won't appear to have gone unrewarded. Wait a few years.
