When we talk of resources we think of books, buildings, staff. But the biggest resource you have is your readers. They are plentiful in number, variety and imagination. Many of them would enjoy having a greater involvement - and they will give of their time and expertise for free!
Use the book knowledge of your readers to expand that of your staff. Use their reading enthusiasms to enhance and personalise your displays. Involve readers in bookchains, reading groups and readers' events and you will have an unending supply of opinions about books as well as a growing audience for reader activities.
Make use of the fact that you know your readers well - you know who would be good at enthusing others, who needs the support of a friend to feel confident, who should be prevented from getting on their personal soapbox and given a different role instead …
Have confidence in your readers and develop their confidence in themselves. You don't need a celebrity to make an enjoyable readers' event. Libraries round the country have run themed evenings - Italian nights, wine and books' tasting, books to fall for (on Valentine's Day). A library in a rural town set up a very popular day festival which simply offered the chance to talk one-to-one for an hour with another reader with set times for different sorts of reading.
