As a retired Chartered Librarian (Librarianship is a profession) I should declare an interest.
Unfortunately public libraries in the UK are in a massive decline caused, IMHO, by political indifference by all parties at all levels. Although a statutory service, what they should do has never been satisfactorily defined and indicators are all quantity – you will get brownie points for issuing an Agatha Christie but not for inspiring a Hawking or an Einstein.
Ideally they should be a neutral source of information accessible by all. Google isn’t the answer to everything; it isn’t even the only search engine. (The height of Nelson’s column is a recent, famous example of something that should have a clearly defined answer– when it was cleaned most of the values quoted on the internet and in many books were found to be wrong – and there were quite a few different heights given varying by nearly 30ft! Even now you’ll find some variation on different sites) The internet is a great tool but you need even more caution using it than when using books.
Libraries should provide information for the beginner as well as more detailed, and often expensive, sources for those who want to dig deeper into a subject and librarians should be able to provide a guide to these sources – authority of the author, alternative views in different sources, etc. I suspect cuts and de professionalisation are the cause of a lot of “dumbing down”.
But to end my rant and get back on topic
Yes, get the leaflets into the library and why not offer to give talks in the library to adults and to children? Most libraries will (or were) happy to host talks and it is a way of connecting with a public who may not otherwise see anything about the hobby.
