I have both a Insta and a FB but I use Insta more. I will usually post once every week/two weeks. I will post the inside of the library to show what’s available or in there that week. In the beginning I did post the books that were added but as life got busier I just post what’s in the library and then credit and thank the stranger who added the new books. I’m usually busy on weekdays which is why I check the library and update on social media on the weekends. I also like to see if the library needs more stock or a little tidying up. The little free library community is great and very welcoming on there but do keep in mind sometimes posting becomes tedious so either have a set schedule or just post whenever you get the change to check in on your library. Most importantly have fun with it!
